In addition to habitat loss and fragmentation, demographic processes—the vagaries of births, deaths and sex ratio fluctuations—pose substantial threats to wild giant panda populations. Additionally, climate change and plans for the Giant Panda National Park may influence (in opposing directions) the extinction risk for wild giant pandas. The Fourth National Giant Panda Census showed pandas living in 33 isolated populations. An estimated 259 animals live in 25 of these groups, ~14% of the total population. We used individual-based models to simulate time series of these small populations for 100 years. We analysed the spatial pattern of their risk of extinction under current conditions and multiple climate change models. Furthermore, we consider the impact of the proposed Giant Panda National Park. Results showed that 15 populations face a risk >90%, and for 3 other populations the risk is >50%. Of the 15 most at-risk populations, national parks can protect only 3. Under the Representative Concentration Pathway 8.5 climate change scenario, the 33 populations will probably further divide into 56 populations. Some 41 of them will face a risk >50% and 35 face a risk >90%. Although national parks will probably connect some fragmented habitats, 26 populations will be outside national park planning. Our study gives practical advice for conservation policies and management and has implications for the conservation of other species in the world that live in isolated, fragmented habitats. The authors model likely outcomes for the 33 isolated populations reported in the Fourth National Giant Panda Census under multiple RCP scenarios and with the provision of the planned Giant Panda National Park. They find that, although the National Park may connect some fragmented habitats, most of the populations with high extinction risk fall outside the current plans.

Environmental degradation caused by rapid urbanization is a pressing global issue. However, little is known about how urban changes operate and affect environments across multiple scales. Focusing on China, we found urbanization was indeed massive from 2000 to 2015, but it was also very uneven, exhibiting high internal city dynamics. Urban areas in China as a whole became less green, warmer, and had exacerbated PM2.5 pollution. However, environmental impacts differed in newly developed versus older areas of cities. Adverse impacts were prominent in newly urbanized areas, while old urban areas generally showed improved environmental quality. In addition, regional environmental issues are emerging as cities expand, connect, and interact to form urban megaregions. To turn urbanization into an opportunity for, rather than an obstacle to, sustainable development, we must move beyond documenting urban expansion to understand the environmental consequences of both internal city dynamics and the formation of urban megaregions.

Beginning in the 21st century, the world entered a stage of the rapid development of land urbanization. In general, land urbanization sacrifices ecosystem service value for economic value. Optimizing the spatial pattern of land urbanization is the best means of balancing economic development and ecosystem service value. Taking China as an example, through remote sensing and GIS methods, this paper studies the basic situation of regional land urbanization and the distribution of other types of ecosystems from 2000 to 2015, assessing the relationship between the characteristics of regional land urbanization and economic growth and the value cost of ecosystem services. The results show that the spatial differences of land urbanization practices in China is significant and that the extensive development of land urbanization is a serious issue; the urbanization speed of provinces and cities with a larger scale of land urbanization is faster; the intensive, economical and centralized utilization of land urbanization is an effective way to improve GDP per unit area; and the ecosystem service value cost of land urbanization varies significantly among different ecosystem types and regions. For example, the loss of the ecosystem service value of wetland ecosystems due to land urbanization is the greatest, and the cost of the ecosystem service value of Inner Mongolia per 100 million yuan of new GDP is 13.1-fold that of Shanghai. Therefore, to improve the GDP output per unit area and reduce the value cost of ecosystem services, this study draws a series of conclusions and puts forward corresponding policy suggestions that clarify the development mode and priority development area of land urbanization.

Tropical island countries are often highly populated and deliver immense ecosystem service benefits. As human wellbeing depends on these ecosystems, proper management is crucial in the resource-rich tropical lands where there is less related research. Though ecosystem service and biodiversity studies are a promising path to inform the ecosystem management for these mostly developing countries, published evidence of using ecosystem service studies in decision making is lacking. The purpose of this study is to provide an overview of ecosystem services and related research in Sri Lanka, examining trends and gaps in how these studies are conceptualized. Out of the considered 220 peer-reviewed articles, the majority of articles (48.2%) were terrestrial and forest related while coastal ecosystems were considered in 33.2% of studies. In most studies, the ecosystem service category studied was provisioning (31.5%) followed by regulatory service (28.7%). Studies investigating and quantifying ecosystem services, pressures on ecosystems, and their management were fewer compared to studies related to biodiversity or species introduction. Moreover, studies investigating the value of ecosystem services and biodiversity to the communities or involvement of stakeholders in the development of management actions regarding the ecosystem services were rare in Sri Lanka, and an intense focus from future studies in these aspects is timely and necessary.

In response to extreme societal consequences of ecosystem degradation and climate change, attention to ecological restoration is increasing globally. In China, investments in restoration exceeded USD 378.5 billion over the past decade. However, restoration programs are experiments that can cause marked unintended consequences, with trade-offs across space and time that have undergone little empirical examination. We quantified the long-term effects of large-scale afforestation for soil erosion and sandstorm prevention in semiarid China. We found that soil erosion was notably reduced by afforestation but surface runoff declined significantly, after a time lag of 18 years, limiting overall benefit. While forest area also increased, forest quality declined, interacting with reduced surface water runoff. Crucially, increased forest water consumption accelerated downstream groundwater depletion, thus intensifying conflicts over water use. The time lags and spatial trade-offs revealed by this case study provide critical lessons for large-scale restoration programs globally.

The spatial heterogeneity of plant diversity at the neighborhood scale has less been understood, although it is very important for the planning and management of neighborhood landscape. In this case study of Beijing, we conducted intensive investigations of the plant diversity in different neighborhoods along a rural–urban gradient. The results showed that the mean numbers of plant species per neighborhood were 30.5 for trees, 18.8 for shrubs, and 31.9 for herbs, respectively. There were significant logarithmic relationships between the numbers of species and patch area, indicating that larger patches within neighborhoods could harbor more plant species. Hierarchical linear modeling showed that the variations in plant diversity within neighborhoods were higher than those between neighborhoods. The number of species increased logistically with both the number of patches within neighborhoods and the number of neighborhoods, suggesting that it is important to sample a sufficient number of patches within neighborhoods, as well as a sufficient number of neighborhoods in order to sample 90% of the plant species during the investigation of plant diversity in urban neighborhoods. So the hierarchical design of sampling should be recommended for investigating plant diversity in urban areas.

Roads have diverse influences on surrounding biodiversity, especially birds. Here, we evaluated the ecological influences of a highway on avian diversity in the Erka Wetland Reserve (Inner Mongolia, China) to guide future road construction projects. Here, avian and plant surveys were conducted along 51 strips spread over nine transects with different habitat matrixes (including degraded grassland habitat). Nineteen bird species were identified, of which 84% were breeding. Alaudidae was the dominant genus, and is a typical, grassland bird guild. Bayesian analyses showed that Alaudidae density was explained by the interaction between distance from the road and vegetation coverage. Alaudidae density increased with increasing road distance only when the vegetation coverage was at least 35%. However, the height of dominant plants had a negative and significant effect on birds. In addition, endangered birds and some common bird species were absent within the road effect zone. We suggest that future road construction in wetland areas should address the direct and combined effects of roads and habitat configuration (and changes) on birds, in a way that enhances both avian diversity and wetland biodiversity conservation as a whole.

Shortfalls and mismatches between the supply and demand of ecosystem services (ES) can be detrimental to human wellbeing. Studies focused on these problems have increased in recent decades, but few have applied land use optimization to reduce such spatial mismatches. This study developed a methodology to identify ES mismatches and then use these mismatches as objectives for land use optimization. The methodology was applied to the Guangdong-Hong Kong-Macao “Greater Bay Area” (GBA), a megacity of over 70 million people and one of the world’s largest urban agglomerations. Considering the demand for a healthy and secure living environment among city-dwellers, we focused on three ES: heat mitigation, flood mitigation, and recreational services. The results showed large spatial heterogeneity in supply and demand for these three ES. However, compared to current conditions in the GBA, our model showed that optimized land use allocation could better match the supply and demand for heat mitigation (number of beneficiaries increased by 15%), flood mitigation (amount of population exposed to flood damage decreased by 37%), and recreation (number of beneficiaries increased by 14%). By integrating land use allocation and spatial mismatch analysis, this methodology provides a feasible way to align ES supply and demand to advance urban and regional sustainability.

Assessments of ecological importance based on static indexes that do not consider service flows frequently underestimate the importance of the Qinghai-Tibet Plateau as a “source”. On the basis of natural environmental characteristics, this study selected six type of ecosystem services for evaluation, including water retention, soil retention, carbon sequestration, biodiversity conservation, sandstorm prevention, and tourism. According to the attributes of each ecosystem service flow, we calculated the flow length and traffic accessibility indexes, using ArcGIS hydrological module and kernel functions separately, to comprehensively analyse the ecological importance levels of the Qinghai-Tibet Plateau. Results showed that after considering the service flows, the ecologically important zone shifted to the core area of the Three River Source Region, such as Zadoi County located in the Tanggula Mountains. The area of extreme importance is mainly distributed in the Yarlung Zangbo River basin, Tanggula Mountains, Hengduan Mountains, and Qilian Mountains, which accounts for 31.7% of the Qinghai-Tibet Plateau, providing approximately 60% of the ecosystem services and having extremely high protection efficiency and protection value. By introducing ecosystem service flow indexes, this study confirmed the ecological importance of core source areas such as the Tanggula Mountains, weakened the space bias caused by not considering the spatial transfer of ecosystem services, and provided technical support for optimizing ecological protection strategies and coordinating regional development.

Global climate change and extensive socio-economic development both act to decrease the ground cover in the semi-arid sandy grasslands of Horqin district, northern China. Loss of ground cover increases the direct exposure of the surface soil to erosion by strong winds—a process that ultimately converts grassland into sandy desert. Three ways to restore such degraded lands through afforestation were evaluated in terms of total carbon stored in the restored ecosystems compared to that in the control. Total carbon comprised that stored in the biomass of trees, herbs, standing litter, and soil (to a depth of 100 cm). The three restoration treatments were (1) enclosing the grassland within a shelter belt of Populus × beijingensis (FG), (2) afforesting small but well-distributed patches within the grassland using Pinus sylvestris var. mongolica (MG), and (3) afforesting small but well-distributed patches within the grassland using Ulmus pumila (UG). A plot of desertified sandy grassland in which the dominant species were Agriophyllum squarrosum (Linn.) Moq. and Cenchrus echinatus Linn. was used as the control (CK). The results show that total ecosystem carbon storage in FG, UG, and MG increased significantly over time in comparison with that in CK. After more than 20 years, all three grassland restoration approaches are expected to contribute greatly to global ecosystem carbon sequestration. The rank order of total ecosystem carbon storage content is: FG (104.29 t/ha) > MG (102.96 t/ha) > UG (92.24 t/ha) > CK (24.48 t/ha). Soil carbon storage in the 0–30 cm and 0–50 cm depth ranges accounted for 41.81–60.13% and 59.42–80.80% of the total soil pool, respectively, across all treatments. FG had the highest biomass carbon storage, which was linked to differences in tree species. The structure of the plant community created in these treatments was different from that found in natural stands of forest and in grasslands without trees or shrubs. All the three treatments are suitable for the restoration of moderately desertified sandy grasslands in south-eastern Horqin, northern China, depending on the availability of water and soil nutrients. The results of the present study highlight the importance of degraded grassland restoration programs in enhancing ecosystem carbon storage.

The ecological civilization construction in China currently demands high-quality development, and a standards system can guide and support the high-quality development of ecological civilization. In this study, we review the strategic demand for the high-quality development of ecological civilization, present the theoretical and practical progress of the standards system, and summarize the problems regarding the construction of the current standards system, such as lack of standards in key areas and a low implementation rate. Moreover, we propose several suggestions for optimizing the framework and content of the standard system and implementation paths for key areas. Specifically, a standards system for realizing ecological product values should be established to support the development of ecological economy; the standards system for ecological and environmental quality should be improved to guarantee national ecological and environmental safety; terrestrial and marine standards systems should be promoted to support territory spatial arrangement; and a green living standards system should be established to regulate the ecological culture construction.

Climate change and human activities exert a wide range of stressors on urban coastal areas. Synthetical assessment of coastal vulnerability is crucial for effective interventions and long-term planning. However, there have been few studies based on integrative analyses of ecological and physical characteristics and socioeconomic conditions in urban coastal areas. This study developed a holistic framework for assessing coastal vulnerability from three dimensions - biophysical exposure, sensitivity and adaptive capacity - and applied it to the coast of Bohai Economic Rim, an extensive and important development zone in China. A composite vulnerability index (CVI) was developed for every 1 km2 segment of the total 5627 km coastline and the areas that most prone to coastal hazards were identified by mapping the distribution patterns of the CVIs in the present and under future climate change scenarios. The CVIs show a spatial heterogeneity, with higher values concentrated along the southwestern and northeastern coasts and lower values concentrated along the southern coasts. Currently, 20% of the coastlines with approximately 350,000 people are highly vulnerable to coastal hazards. With sea-level rises under the future scenarios of the year 2100, more coastlines will be highly vulnerable, and the amount of highly-threatened population was estimated to increase by 13–24%. Among the coastal cities, Dongying was categorized as having the highest vulnerability, mainly due to poor transportation and medical services and low GDP per capita, which contribute to low adaptive capacity. Our results can benefit decision-makers by highlighting prioritized areas and identifying the most important determinants of priority, facilitating location-specific interventions for climate-change adaptation and sustainable coastal management.

Effective provision of ecosystem services (ES) and improvements in well-being of residents can be realized through policy interventions of stakeholder behavior. Among the many policies, market-based instruments (MBIs) have become the focus of global attention, despite a package of practical difficulties. As the market has the advantages of flexibility and low transaction costs, MBIs remain a comprehensive mechanism to translate the external, non-market values of ES into real financial incentives for local actors to provide such services. To couple the theory with practice and solve the key problem of unclear definition of property rights, the framework of MBIs is designed. First, property rights of market creation must be clearly defined, verifiable, transferable, enforceable, and have policy continuity. Then, four key characteristics of MBIs need to be considered in the case design, namely those involving ES, stakeholders, trading mechanisms, and guarantee mechanisms. The Pledge Financing of the Right of the Ecological Public Welfare Forest (PFREPWF) in Lishui City is a typical case of China’s current marketization, which is a supplement and improvement to the ecological compensation policy. Based on clearly defined contract rights, Lishui City has realized the integration of ecological compensation and credit creation. PFREPWF reflects the value of the ecological public welfare forest and also solves the problem of insufficient participation of forest farmers due to their affected livelihoods. However, the case design still has the problems of lack of quantification and lack of correlations with ES. The theoretical and practical analysis around the market mechanism has reference value for solving market failures and providing environmental services. Graphical abstract

The population aggregation and built-up area expansion caused by urbanization can have significant impacts on the supply and distribution of crucial ecosystem services. The correlation between urbanization and ecosystem services has been well-studied, but additional research is needed to better understand the spatiotemporal interactions between ecosystem services and urbanization processes in highly urbanized areas as well as surrounding rural areas. In this paper, the relationships of urbanization with natural habitat and three key regulating ecosystem services—water retention, soil conservation, and carbon sequestration, were quantified and mapped for the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), a rapidly developing urban agglomeration of over 70 million people, for the period of 2000–2018. Our results showed that urbanization caused a general decline in ecosystem services, and urbanization and ecosystem services exhibited a negative spatial correlation. However, this relationship varied along urban-rural gradients and weak decoupling was the overall trend during the course of the study period, indicating a greater need for the protection and improvement of ecosystem services. Our results provide instructive insights for new urbanization planning to maintain regional ecosystem services and sustainable development in the GBA and other large, rapidly urbanized agglomerations.

Residential communities are the primary living spaces for people in China. Their associated greenspaces are important elements of the urban ecosystem, providing neighborhood ecosystem services and hosting bird populations of differing community structures compared with other urban green areas. This study analyzes avian community characteristics within residential communities and their differences compared with urban parks in Beijing. Furthermore, we assess the key environmental factors determining species composition and population sizes and the spatial scales at which these factors are most significant. We randomly selected 27 residential communities to assess the habitat structure and landscape characteristics that underpin residential avian assemblages across multiple spatial scales. Independent sample t test and model selection methods based on AICc were used for data analysis. Eurasian Tree Sparrow (Passer montanus) (hereafter ETS) alone accounted for 91.0% of total individuals. Compared with urban parks, more migrants and omnivores were found in residential communities. Within-site forest patch connectivity simultaneously decided resident species diversity and individual abundance, with the exception of ETS. Tree species richness and coverage are key predictors for resident species richness and ETS numbers, respectively. Even in the most urbanized species, ETS retained ecological attributes found in “wilder” settings. Residential communities skewed toward avian communities with dominant numbers of ETS. In these low-quality habitats, our results suggest that landscape configuration is more important than local habitat structure. Within-site habitat connectivity and the number of surrounding forest patches with shorter between-patch distances deserve more attention in future landscape design for residential communities.

Ecosystem degradation can lead to adverse consequences and disasters and hence, a healthy ecosystem is imperative for human well‐being. As a country with a large population and area, China's ecological security has global significance. To determine the effect of existing land use and relevant policies on the ecosystem, we need to understand the current situation of China's ecological degradation and restoration. However, relevant research at the national scale is lacking. We used remote sensing and GIS methods to study the extent, type, and composition of ecological degradation and restoration in China, at the national scale, from 2000 to 2015. The results revealed that the fundamental cause of China's ecological degradation was development and construction, and this kind of degradation is difficult to recover from. In the 15 years, the restoration area of this type of ecological degradation accounted for only 11% of the total degraded area. The total area that was newly constructed was 87,961.04 km2, of which 66,176.04 km2 was previously cultivated land. For food security, another 75,258.36 km2 of cultivated land was reclaimed. The two types of ecological degradation accounted for 71.59% of the total degraded area, and the increasing farmland area alone caused 42.14% of wetland degradation. Existing restoration projects are generally effective, but degradation, especially desertification, in the arid and semi‐arid regions of the northwest still needs special attention. Above all, ecological protection should be the focus, while ecological restoration the remedy. This article is protected by copyright. All rights reserved.

The Convention on Biological Diversity’s Aichi Targets address both biodiversity and ecosystem services. We explore the relationship between giant panda populations and three ecosystem services: carbon sequestration, water retention, and soil retention. Do pandas prefer areas with higher than average values of these services? Areas may be good for pandas but not for these ecosystem services, and vice versa. Answering these questions can focus panda conservation. We map their spatial distribution and temporal changes from 2000 to 2015, by watershed, to target future protected areas for both pandas and these ecosystem services. Pandas occupy watersheds with above-average carbon sequestration and water retention. There is no tendency for pandas to be increasing in watersheds that have higher than average values of these ecosystem services or in watersheds where they are improving. Protected areas represented watersheds with higher than average values of these ecosystem services but without pandas only poorly. Watersheds with pandas do provide higher than average ecosystem services, but watersheds above average for these ecosystem services often lack pandas. Those areas might be potentially important for pandas, but obstacles block their way. We identified conservation areas combining habitats, population, activity range, and higher than average values of these ecosystem services and then proposed new protected areas.
