Land degradation caused by wind erosion seriously threatens the supply of ecosystem services on the Qinghai-Tibet Plateau (QTP). Assessing wind erosion variations is critical to identify key change areas and formulate desertification control strategies. In this study, we evaluated the spatiotemporal dynamics in wind erosion on the QTP from 1980 to 2015 using the Revised Wind Erosion Equation (RWEQ). Furthermore, we analysed the spatial correlation between wind erosion dynamics, climate change and human activities and identified the main driving factors. The results showed that wind erosion intensity on the QTP increased continuously from southeast to northwest. Areas with moderate or high soil erosion intensity (>25 t·hm−2·a−1), accounting for 53.48% of the region, were mostly distributed on the western and northern areas of the plateau. The mean annual soil wind erosion modulus (SWEM) of the entire region during 1980–2015 was 32.08 t·hm−2·a−1, with an evident decline at a rate of approximately 0.14 t·hm−2·a−1 in this period. However, wind erosion increased significantly in 9.99% of the QTP, mainly in the northwestern part of the region. Areas with significant changes in wind erosion driven by climate change and human activities accounted for 54.74% and 18.89% of the plateau, respectively. The influence of climate change on wind erosion is characterized by large scale and spatial continuity, while the impact of human activities on wind erosion occurs in local areas and distributes in patches. This study has implications for spatially revealing the climate and human drivers of wind erosion changes and identifying pivotal zones for desertification prevention on the QTP.

Tree species and afforestation age can affect soil carbon (C) and nitrogen (N) sequestration as well as soil properties through different litter input and microbial activities. However, uncertainty remains because the responses vary under different climates and prior land uses. A site-specific study was conducted to investigate the dissimilarities in plant litter, soil properties, and soil microbial biomass and their influencing factors of different aged (22, 32, and 44 years) larch (Larix principis-rupprechtii) plantations and different aged (19, 30, and 43 years) Mongolian pine (Pinus sylvestris var. mongolica) plantations. In general, afforestation increased soil organic carbon (SOC), soil total nitrogen (STN), soil microbial biomass carbon (MBC), and soil microbial biomass nitrogen (MBN) contents compared with those of sparse grassland. However, there was still room for improvement in these variables compared with local natural secondary forest, which was dominated by white birch (Betula platyphylla, a deciduous broad-leaved tree species). Changes in STN, SOC, MBC, and MBN contents with afforestation age were almost insignificant in larch plantations, while significant increase can be found in STN (only in 10–20 cm soil layer), MBC and MBN in Mongolian pine plantations. The results indicated that larch was superior to Mongolian pine in soil C and N sequestration and soil fertility improvement at an early afforestation stage probably because of the higher C and N inputs from litter and higher N supply in the soil. There is an upper limit of carbon and nitrogen sequestration and soil fertility in the coniferous plantation, and mix planting of broad-leaved trees in coniferous forests may make up for this disadvantage. This study provided a reference for the selection of afforestation tree species in northern China and other areas with similar climatic conditions.

Faced with climate change, rapid urbanization, and ecosystem degradation, comprehensive analyses of both the carbon balance are urgently required to achieve the envisioned sustainable development goals. This study proposed an integrated framework incorporating land use dynamics and carbon balance into the urban management system, according to the logic of “Background & objectives-Carbon balance-(Natural system + land use and land cover change + Socio-economic system)-Policy & strategy”. This is followed by the case study and specific policy implications of the Beijing-Tianjin-Hebei (BTH) region, a typical urban agglomeration in China. Results show that the land use structure of the BTH region remained relatively steady from 2000 to 2015. Cultivated land is primarily distributed in the southeast, with a slight decrease from 51% in 2000 to 48% in 2015. Carbon emissions from built up land have the highest proportion and increased from 82.58% in 2000 to 92.43% in 2015. Carbon sinks are mainly found in the northwest and carbon sources are mainly found in the southeast. The carbon balance is increasingly unsettled, with a sharply decreasing rate from 2.7253% in 2000 to 0.6623% in 2015. Comprehensive policies are proposed from four specific aspects, i.e., strengthening of land governance, land use planning, optimization of the industrial structure, and regulation of residential behavior. The results and conclusions provide scientific evidences for the regional spatial management, to achieve sustainable development.

Alpine grasslands on the Qinghai-Tibet Plateau (QTP) provide irreplaceable ecosystem services to local and global communities. However, intensive human activities have caused severe grassland degradation during recent decades. Due to the harsh environment, these degraded grasslands recover slowly or may be irrecoverable after they degenerate to a certain stage. To understand the changes in the resilience of alpine grassland on the QTP after degradation, we evaluated the resilience indexes of the plant, soil and plant-soil systems of grasslands at different degradation stages based on an integrated assessment system and data extracted from 53 published studies in this region. The results showed that,with grassland degradation, most plant indicators including plant height, aboveground biomass, belowground biomass, Cyperaceae, Gramineae, and soil indicators including silt, clay, soil organic carbon, soil total nitrogen, available nitrogen, available phosphorus, available potassium, and soil water content gradually decreased; soil variables including sand, bulk density, and soil temperature showed an increasing trend; and Margalef richness index, Shannon-Wiener index, Pielou evenness index, and forbs first increased and then decreased. The resilience indexes of the plant, soil and plant-soil systems all displayed an obvious downward trend with the increase of degradation degree, which indicates that reduction of grassland resilience is the coordinated degeneration of vegetation and soil. To restore degraded grassland, we should focus on improving both soil and vegetation status to enhance the resilience of grassland ecosystems.

Since the beginning of the 21 st century, China’s urbanization has developed rapidly. In line with the steep trajectory of urbanization, the Chinese government has strengthened the environmental management and ecological protection. Driven by these policies, the country’s comprehensive urbanization level (CUL), including demographic, economic, land use and social aspects, and energy eco-efficiency (EE) have changed over the years. However, few studies have analyzed the changing trends of CUL and EE, especially their coupling coordination degree (CCD). In light of this research gap, this study takes 281 prefecture-level cities as the study objects with which to evaluate and analyze the spatial-temporal change trends of CUL, EE and their CCD, from 2006 to 2016. The conclusions show the following: (1) China’s CUL changed dynamically over time and showed a significant distribution in space. (2) The EE of all cities improved to varying degrees. (3) The CCD manifested an increasing trend, which promoted China moving toward a high coordination level. (4) The urbanization level hindered the further improvement of the CCD. Thus, the Chinese government should improve urbanization quality. These findings and conclusions can provide useful decision-making information for policymakers as they manage cities and improve the CCD between CUL and EE.

Global climate change, rapid urbanization, and drastic economic development pose many threats and challenges to humanity, increasing the necessity for sustainable human development, urban ecological management, and low-carbon transformation. The current studies on urban management model are relatively scattered, while most of them focus on one-dimensional and problem-oriented measures. Firstly, we review the history of urban ecological management's development, including four stages, i.e., the germination, transitional, formative, and prosperity stage, and summarize the concepts related to eco-cities. Then, we present a comparative analysis of the typical urban ecological management models worldwide, with a focus on Singapore's garden city, Japan's zero-waste city, Britain's low-carbon city, Brazil's green state capital, Australia's eco-city, Finland's eco-city development projects, and the United States' comprehensive management. Three other typical models from Sweden, Germany, and Denmark are presented. The experiences and lessons from these urban ecological management models are further discussed. Finally, a new and comprehensive management framework is proposed, incorporating the five perspectives of urban planning, industrial transformation, organizational model, environmental protection, and institution system. The framework can provide a scientific basis for the refinement of urban ecological mangement. All the analysis and conclusions will contribute to the academic research and practical operations regarding low-carbon transformation and regional sustainable development.

The Bashang Plateau, which is an ecologically fragile agro-pastoral zone in Hebei Province in China, plays an important role in protecting the Beijing-Tianjin-Hebei region from wind and sand erosion. Over the last four decades, it has been the target of extensive afforestation campaigns to promote improved ecosystem services. Though the benefits and costs of afforestation and its effectiveness within forestry have been widely investigated, few studies have focused on local households' willingness to accept (WTA) compensation relating to afforestation policies. Moreover, despite their importance in ensuring effective afforestation policies, the factors influencing WTA values have seldom been examined. We administered a direct questionnaire survey of households on the Bashang Plateau and applied a contingent valuation analysis to estimate their WTA values for compensation associated with ecological protection policies. We obtained 249 valid questionnaires, evidencing a high response rate (92.22%). New indicators of factors influencing respondents' WTA has been conducted including social, economic and ecological aspects, especially the improvement of ecological factors which consists of respondents' perceptions regarding the importance of ES and their satisfaction levels, and other environmental awareness factors. Additionally, in the case where many studies performed only one single regression analysis, this study performed a two-stage regression analysis and compared the results with those obtained using the Tobit model. A reasonable compensation standard facilitates a positive relationship between economic development and protection of natural environments. The findings showed that a certain amount of compensation (approximately 477.91 CNY/mu/year) was likely to prompt households' participation in afforestation projects. Compared with compensation standards for other ecological projects, the reported standard for afforestation projects on the Bashang Plateau is low, indicating that there is room for improvement. High annual household incomes are a key factor influencing households' WTA regarding their participation in afforestation activities. The results also revealed households' environmental awareness. Among respondents who participated in afforestation, those who valued forests for protecting environments and improving ecosystem services opted for lower compensation amounts. Our findings contribute valuable inputs for formulating ecological compensation standards and can serve as a reference for analyses of WTA and factors that drive it in other similar economically backward and ecologically fragile regions.

Forests are the most important renewable resources and provide critical ecosystem services worldwide, especially the provisioning service, making a great contribution to human well-being. The Three-North Shelter Forest Program (TNSFP) is a large-scale ecological project aimed at improving ecological environments and consolidating economic construction in China through the development of artificial forests. In our study, stochastic frontier analysis was adopted to estimate forest production efficiency (FPE) by using dynamic panel data. Based on the FPE of 13 provinces located within the TNSFP region during the period 2000–2016, the effects of the natural and socioeconomic influencing factors on FPE were further explored by using the Tobit regression model. The estimated results confirmed the validity of the constructed model and revealed an increasing trend of the mean annual FPE value, which ranged from 0.3147 in 2000 to 0.5681 in 2016. The FPE was declining from the eastern region to the western region in 2000. However, this spatial distribution characteristic changed enormously in 2016; regions with low FPE were in the center of the TNSFP region, surrounded by the regions with high FPE. Moreover, the following factors positively influenced FPE: average temperature (1.4476), total annual rainfall (0.0800), per capita GDP (0.0882), the education levels of forestry employees (0.2120), the number of forest technology stations in townships (0.0149), and disease and pest control areas (0.0190). However, the impacts of the policy relating to the Natural Forest Protection Program on FPE were insignificant. These influencing factors had differential effects on FPE within the TNSFP’s three sub-regions during the period 2000–2016. These findings can contribute to more efficient forest management and strengthen resource and environment management.

Carbon emissions have become a global environmental problem in recent years. It is necessary to explore methods to improve the efficiency of energy consumption and minimize carbon emissions that accompany economic development and rapid urbanization. In this paper, we quantitatively measure the total factor carbon emission performance (TFCP) and the carbon emission mitigation potential (CMP) of 39 industrial sectors in the Beijing–Tianjin–Hebei (BTH) region from 2010 to 2016 by employing a stochastic frontier approach. The results show that the average TFCP value of the 39 industrial sectors in the BTH region was relatively low (0.7733). From 2010 to 2016, the TFCP increased in Beijing, decreased in Tianjin and held steady in Hebei. The entire level of TFCP in Hebei was the greatest, followed by Tianjin and Beijing. The CMP in the BTH region increased slightly during the period 2010–2016. The total CMP of the 39 industrial sectors in the BTH region was 11.03 × 108 t from 2010 to 2016. The industrial sectors were divided into four categories according to the relationship between the TFCP and CMP. Belonging to the low TFCP–high CMP quadrant, the Manufacture of Nonmetallic Mineral Products sector and the Production and Distribution of Electric Power and Heat Power sector should attract more attention when formulating carbon reduction policies and related regulations. According to the results, we also present suggestions to strengthen green economic growth and regional sustainable development.

Forest ecosystems are a major component of the terrestrial ecosystems as they provide a variety of important ecosystem services, especially climate regulation via carbon sequestration. The Three-North Shelterbelt Program (TNSP), a pioneer for China's large-scale ecological construction, has promoted massive afforestation and forest dynamics since 1978. Quantitative analysis of carbon sequestration and its economic value of sub-type forest landscapes in the TNSP region is crucial for better understanding the capacity of forest carbon sequestration and providing reasonable forest management. Therefore, we assess the forest carbon sequestration in the TNSP region using the InVEST model based on spatial datasets during 1990–2015. Our results showed that forests in the TNSP region had strong carbon sequestration capacity. Total carbon sequestration fluctuated and overall showed a decreasing trend, with a reduction rate of 1.92% during the period of 1990–2015. The carbon sequestration of each carbon pool (namely aboveground biomass, belowground biomass, soil, and dead organic matter) also decreased slightly and the changes mainly happened in the north of northeastern China and along the southeast of central north China. Additionally, in monetary terms, the economic value of carbon sequestration reflected that the TNSP was worth implementing, with a small amount of investment in exchange for large carbon sequestration benefits. This work provides an up-to-date attempt to calculate carbon sequestration of forest more accurately, quantify economic values of carbon sequestration for forest ecosystems, which will give a baseline reference for related studies in the TNSP region, as well as other similar reforestation area.

Ecosystem services value has decreased rapidly caused by land use/land cover changes driven by urbanization during the past decades. Expanding urbanization not only changes the spatial distribution of areas of ecosystem service demand but it also changes the potential functions of ecosystem services. It is necessary to undertake a quantitative analysis of historical changes in land use/land cover in the context of the urban land sprawl to better understand existing relationships between ecological services and land use/land cover change. The methodology for this study was derived from an established knowledge base on the importance of land use/land cover types for the supply of each of nine identified ecosystem services extracted from a review of the literature. We selected the Pearl River Delta as the object of our study and used a land-use dataset entailing a resolution of 100 m to analyze the land use/land cover change trends and the values of ecosystem services in this region from 1990 to 2015. Furthermore, we compiled a summary of changes in the values of ecosystem services caused by changes in land use/land cover. We found that the change trend of land use/land cover in the Pearl River Delta, which is dominated by forests, reflected a highly dynamic context. Construction land increased from 2909.77 km2 to 7486.89 km2 over the study period. The total value of ecosystem services increased by 4.5 × 1021 seJ during the period 1990–2015. Individual ecosystem services that contributed the greatest value were hydrological regulation, climate regulation, and soil formation and retention. In light of our findings, we developed a matrix of ecosystem service values in relation to land use transitions and explored its policy implications for ecosystem management. This matrix can help decision makers to better understand tradeoffs between ecosystem services caused by land use/land cover changes.

Economic development has promoted urbanization in the Beijing-Tianjin-Hebei (BTH) region. With the improvement of living standards, residential consumption have become an important contributor to regional carbon emissions. Using an input-output model, we calculated direct and indirect carbon emissions from both urban and rural residential consumption in the BTH region from 2002 to 2012, and then explored the main factors contributing to indirect carbon emissions from residential consumption using a structural decomposition analysis. Results showed that direct carbon emissions from residential consumption increased from 47.13 million tons (MtC) in 2002 to 123.34 MtC in 2012 and indirect carbon emissions from residential consumption increased from 210.36 MtC in 2002 to 550.00 MtC in 2012. Carbon emission intensity and residential consumption level were the main factors affecting indirect carbon emissions during 2002–2012, with varying effects in different sub-regions. Carbon emission intensity played negative effects in Beijing (-37.19 MtC) and Tianjin (-55.39 MtC), positive effects in Hebei (92.89 MtC). Residential consumption level played positive effects in the three sub-regions (79.94 MtC in Beijing, 31.91 MtC in Tianjin and 155.52 MtC in Hebei respectively). Increases in intermediate demand, residential consumption level and population size enhanced indirect carbon emissions. Based on the analysis, this paper contributed to the carbon emission reduction strategies in the BTH region.

Against the background of new urbanization, urban agglomeration plays an important role in boosting development in surrounding areas. It is important that energy consumption is reduced and energy productivity improved. The Pearl River Delta Metropolitan Region (PRD) is one of the most promising city agglomerations in China. Therefore, based on data sourced from China City Statistical Yearbooks (2006–2016) and Guangdong Statistical Yearbooks (2006–2016), a global Malmquist–Luenberger productivity index is adopted to analyze the change trends of energy productivity growth in the PRD during 2005–2015. The estimation results show that there are differences among the change trends of energy productivity growth in the nine cities in the PRD, and that productivity growth improved during the study period. The greatest contributor to energy productivity growth is technological progress. We also identified the key determinants affecting energy productivity growth using generralized least squares regression and found that industrial structure, openness index and capital per capita have a positive effect. The energy price, energy intensity, per capita of GDP, R&D intensity and government regulation have a negative effect on energy productivity growth. These conclusions inform decision makers in improving energy productivity and coordinating economic development and environmental protection in the PRD.

Land use and land cover change (LUCC) has had a profound effect on terrestrial carbon stocks, though its impact on the terrestrial carbon cycle remains uncertain. LUCC and rapid urbanization have occurred in the Beijing–Tianjin–Hebei (BTH) region over the past decades, which have greatly influenced regional carbon stocks. Based on the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model, this paper estimated the temporal and spatial variation of carbon stocks in the BTH region from 1990 to 2015 and explored the relationship between carbon sequestration and urbanization level at the county scale. Our results showed: (1) There was a built–up land expansion (5795 km2) at the expense of other land use types (−5548 km2, including cultivated land, woodland and grassland). (2) The total carbon stock of the BTH region decreased from 40.55 × 108 t in 1990 to 40.04 × 108 t in 2015. The soil organic matter stock accounted for more than 60% of the total carbon stock. (3) Carbon density decreased from northwest to southeast in the BTH region. Meanwhile, carbon stocks for 134 county districts decreased (carbon sources), while the other 26 county districts increased (carbon sinks) from 1990 to 2015. (4) The urbanization level had a clear influence on carbon sequestration in the BTH region at a county scale and showed significant negative correlations. Our results provide a unique perspective on LUCC and ecosystem services, which can influence the implementation of regional planning and policy.

Under the background of new urbanization, urban agglomeration plays an important role in boosting development in surrounding areas. However, while contributing significantly to economic growth, it was accompanied by high levels of energy consumption and emissions of waste gas and water into the surrounding ecological system. Therefore, it is worthwhile measuring the environmentally sensitive productivity changes during the development process. The Malmquist–Luenberger index based on company data for the period 2007–2012 is used to examine both desirable and undesirable outputs for total factor productivity of various industrial sectors in the Pearl River Delta. The trend in productivity growth and indexes in efficiency and technology are analyzed. We find that at the city scale, the industrial productivity levels in Dongguan, Shenzhen, and Zhongshan increased during the study period, while those in other cities decreased. Furthermore, Guangzhou, Dongguan, Foshan, Jiangmen, Shenzhen, and Zhuhai are green development cities. Technological advance was the main contributor to productivity growth. In accordance with the efficiency and technological change indexes, 225 Decision-Making Units (DMUs, refers to industrial sectors in this study) comprising specific industries from nine cities were classified into six categories. It was found that 66.9% of the DMUs developed with improved productivity and 40% developed in a green mode. Conditions and trends of industrial sectors and the key determinants affecting environmentally sensitive productivity growth was specified. Thus, it provides essential information for companies to develop in green way, as well as providing policy makers with an understanding of industrial development at both the city and sector level.

Food security has always been a major issue for most regions or nations across the world. Its complete definition covers productivity, ability and accessibility. In remote and less developed areas, food supply mainly depends on self-sufficiency rather than regional commercial trade. Given limited resources, it is necessary to evaluate agricultural production in this kind of area, so as to improve long-term and stable food production to achieve food security. Heihe River Basin (HRB) is famous for its arid and semi-arid climate, as it is located in the inland of Northwest China. Taking the Heihe River Basin as case study area, we analyzed the total factor productivity of 11 counties of the HRB over 1990–2012. Further, agricultural production efficiency was estimated based on Data Envelopment Analysis and the Malmquist index, in which four input indicators (sown area, agriculture and farm labor, general agricultural machine power and fertilizer) and one output indicator (gross agricultural production) were taken into consideration. The results showed that agricultural production was unbalanced in the HRB for the entire period between 1990 and 2012. The agricultural scale efficiency remained basically unchanged in the HRB, and technical change was the main influencing factor on agricultural production.

Land use/cover change (LUCC) in Northeastern China (NEC) has dynamically changed over the past several decades. However, few LUCC studies have examined the value of ecosystem services (VES) in major grain production areas involved in national food production. Measuring this process and incorporating VES into agricultural management can provide a scientific basis for environmental management and sustainable agricultural development. Thus, taking NEC as an example, based on modified value coefficients, we estimated changes in VES in response to LUCC over the past 25 years (1990–2015), and changed VES over this period were incorporated into agricultural management. We found that VES decreased by 27.24% and increased by 61.57% during the periods of 1990–2000 and 2000–2015, respectively. In addition, total VES increased by 17.55%. The decrease of VES during the period of 1990–2000 resulted from cultivated land reclamation, forest and wetland degradation. VES increase was influenced by land retirement and afforestation programs implemented in NEC. When changes in VES were incorporated into agricultural management, small farms appeared to be going down remarkably compared with those for mid-sized and large farms. Prudent agricultural management should be considered for mid-sized and large farms to ensure greater ES-related benefits to humans.

Circular economies are critical for alleviating resource pressure and improving environmental quality at regional level. Emergy analysis and eco-efficiency evaluations play important roles in measuring regional eco-efficiency and providing supporting information for governmental decision-making. In this study, emergy analysis and input–output analysis were applied to analyze the changes in emergy structure, functional efficiency, and sustainable development capacity of Zengcheng, Guangzhou during the period 2000–2016. The results showed that the proportion of non-renewable emergy in total emergy structure of Zengcheng increased from 55% to 75%, which placed a greater environmental load on the natural ecosystem and gradually weakened the capacity for sustainable development. The rates of emergy utilization and eco-efficiency both showed increasing trends. All indicators about eco-efficiency showed the development of Zengcheng heavily relied on emergy consumption, especially on non-renewable emergy. The relationship between emergy utilization and socio-economic development of Zengcheng can provide decision-making support for economic structure optimization and sustainable community development.

China is the fastest urbanizing area in the world. The complex urban systems not only create more socioeconomic output (such as GDP), but also bring more infrastructural costs and environmental losses. Thus, urban research has concentrated on urbanization efficiency toward efficient and spatially coordinated instead of urban size. In this paper, we use data envelopment analysis (DEA) to estimate how well districts in Shanghai utilize their resources. Based on data for five inputs and three outputs, we applied an input-oriented BBC Model and an output-oriented CCR Model for Decision Making Units (DMUs) assessment and urbanization efficiency analysis. In addition, the spatial pattern of relative urbanization efficiency is examined by spatial autocorrelation model. The research result indicates that it is in downward trend mainly affected by technical constraints, 11 out of 17 districts in Shanghai are efficient, and the urbanization efficiency gap between Pudong New district and Huangpu district is significant. The districts’urbanization efficiency in south areas are higher than that in middle and northeast area.

Ecosystem services are tightly coupled with availability of solar energy and its partition into energy fluxes, and biomass accumulation, which represents the energy flux in ecosystems, is a key aspect of ecosystem services. This study analyzed the effects of climate change and land use and land cover change (LUCC) on the biomass accumulation change in the Lower Heihe River Basin during 2001–2010. Biomass accumulation was represented with net primary productivity (NPP), which was estimated with the C-Fix model, and scenario analysis was carried out to investigate effects of climate change and LUCC on biomass accumulation change in a spatially explicit way. Results suggested climate change had an overall positive effect on biomass accumulation, mainly owning to changes in CO2 concentration and temperature. LUCC accounted for 70.61% of biomass accumulation change, but primarily owning to fractional vegetation change (FVCC) rather than land conversion, and there is a negative interactive effect of FVCC and climate change on biomass accumulation, indicating FVCC resulting from water diversion played a dominant in influencing biomass accumulation. These results can provide valuable decision support information for the local ecosystem managers and decision makers to guarantee sustainable provision of essential ecosystem services.
