Using field slope farmland plots, this study planted the typical crop of maize (Zea mays L.) and investigated the effects of varied chemical fertilizer (organic compound fertilizer of potassium nitrate, containing 17% each of nitrogen, phosphorus, and potassium) application levels (0.5 times the common fertilizer amount (CK, 0.75 t·hm−2 to 2.5 CK) on the soil fertility in the Yuanmou dry-hot River Valley. The results showed that the soil chemical properties, microbial properties, and enzyme activities increased with the increase of fertilizer application levels from CK to 2.0 CK. However, a declining trend showed both under 0.5 CK level and the 2.5 CK level, and higher in fertilizer application level 3 (1.5 CK) and level 4 (2.0 CK) compared to level 1 (1 CK). Soil chemical properties, microbial properties, and enzyme activities in five-degree slope cropland topsoil were higher than these in 10-degree slope cropland topsoil. Five parameters (available N, nitrifying bacteria, inorganic phosphorus bacteria, organic matter, and invertase) in five-degree slope cropland and three parameters (organic matter, ammonifying bacteria, and total P) in 10-degree slope cropland, which had the greatest weight in the principal components analysis, were selected to calculate the soil quality index (SQI). The SQI calculated by integrating all critical parameters indicated that the highest SQI values were found in fertilizer levels 1.5 CK (0.71) and 2.0 CK (0.69), followed by CK (0.64), and the lowest were found in 0.5 CK (0.62) and 2.5 CK (0.61) in five-degree slope cropland soil. The highest SQI values were found in fertilizer levels 1.5 CK (0.26) and 2.0 CK (0.29), followed by CK (0.23), and the lowest were found in 0.5 CK (0.14) and 2.5 CK (0.20) in 10-degree slope cropland soil. The final SQI values implied that the fertilization treatment 2 (CK), fertilization treatment 3 (1.5 CK) and fertilization treatment 4 (2.0 CK) could improve the soil fertility, whereas the fertilization treatment 1 (0.5 CK) and fertilization treatment 5 (2.5 CK) could decrease the soil fertility. In view of the impact of slope, the soil qualities of five-degree slope cropland of five fertilization treatments were higher than in 10-degree slope cropland. The SQI values in five-degree slope cropland soil were found higher than the SQI values in 10-degree slope cropland soil by 68.65%, 64.20%, 62.22%, 57.46%, and 67.01%, respectively. For this study, the range of fertilization tolerance was 0.75–1.50 t·hm−2 (organic compound fertilizer of potassium nitrate) in 10-degree slope plot scale and 0.75–1.13 t∙hm−2 in five-degree slope cropland soil.

The Grain for Green Program which is an important part of the strategy of Western development was initiated to protect the ecological environment and mitigate disasters. The upper reaches of the Min River basin is one of the key pilot regions for Grain for Green Program implementation in the mountainous areas of Sichuan Province, southwestern China. Therefore, monitoring the effect of the Grain for Green Program on the ecosystem services (ESs) in the montainous areas is important. Especially, several authors have emphasized the need to quantify spatial characteristics and evaluate ES values of land uses in mountainous areas from spatial and temporal perspectives. In this study, we firstly analyzed the spatial pattern of land uses in mountainous settlements before and after implementation of Grain for Green Program in the upper reaches of Min River, Sichuan Province of China. Based on lacunarity analysis, we explored the spatial characteristics of land uses including spatial heterogeneityand cluster. The results suggested that the spatial characteristics of land uses occurred at different scales, and there is strong relationship between spatial characteristic scales and the different distribution pattern of land use. We then quantified the relationships between geometrical features for land use pacthes and vegetation habitat suitability by multilevel Bayesian model. We found that the vegetation habitat suitability significantly affected on spatial location, size, and complexity of different land use patches in mountainous settlements. Based on assignment method of ES value per unit area, we finally quantitatively analyzed and compared the changes in ES values of land uses in mountainous settlements caused by Grain for Green Program from spatial and temporal scales. It is an important indicator for defining ecological potential by quantifying the change in ES value. After implementation of Grain for Green Program, the total ES value dramatically increased because of increase in forest and pasture areas. It suggests that the Grain for Green Program could bring effectively ecological benefit on protecting ecosystem functions in some degree. Application of spatial characteristics analysis of land uses and ES valuation in mountainous settlements to study the spatial structure of land use and service supplies should provide a better understanding of service provision and enable evaluation of the ecological integrity of land uses in mountainous areas.

The ecosystem services provision is constantly under threat by anthropogenic pressures, especially which is mainly related to land use changes. A solution proposed to address these issues is the implementation of spatial characteristics of land uses and ecological compensation (based on Payment for Ecosystem Services) programs. In this study, we developed a framework for analyzing the spatial characteristics of land uses and calculating ecological compensation from 2000 to 2015 in Sichuan Province, China. We firstly examined the utility of lacunarity analysis for detecting spatial characteristic scales of pattern of land uses. Due to large-scale and regular distribution, the spatial heterogeneity of cropland, woodland and grassland were higher than that of water body, construction land and unused land. We then investigated changes in ecosystem services in response to land use change through assignment of per unit area ecosystem service value method. The total ecosystem service value is about 10,780 billion yuan·year−1, and the woodland and grassland ecosystems contributed more to the total ecosystem service value. The critical areas (with higher ecosystem service value) for management purpose were identified depending on the heterogeneity of use services learned from spatially explicit measures. Considering the changed relationship between social and economic indicators and ecosystem service value based on spatial visualization and analysis, we finally constructed a quantitative estimate model for ecological compensation taking city (state) as study unit, and determined standard value so as to evaluate ecological compensation from 2000 to 2015. Spatial differences of the ecological compensation were significant among all the cities (states). The average payment standards of ecological compensation based on the population, ecological compensation based on city (state) area, and corrected ecological compensation were − 117.10 billion yuan, 4.41E-13 billion yuan, and − 58.55 billion yuan, respectively. The negative values suggested that the stakeholders of Sichuan Province should pay for ecological compensation, and the positive value meant the residents in the Sichuan Province can obtain the amount of ecological compensation. This proposed innovative framework provides a better understanding of spatial characteristic scales of land uses and enables evaluation of the ecological integrity of landscapes. It also fills up the gap in the field of quantitative evaluation of regional ecological compensation and provides a feasible way to reconcile the conflicts among benefits in the economic, social and ecological sectors.

Considered as a hotspot for biodiversity in the upstream of Yangtze River, many vegetation habitats have been seriously damaged in Upper Reaches of Min River located in Sichuan Province, China due to the continuous deterioration of ecosystems. This work aims to define important protected areas with higher vegetation habitat suitability index. Through integrating the spatial distribution of vegetation habitat suitability (HS) index into systematic conservation planning, this study constructed spatial priority conservation areas of vegetation habitat under different protection targets in the Upper Reaches of Min River, China. In this regard, effective information regarding vegetation HS and its priority conservation planning responded to conservation target level changes and boundary length effect provide useful support for diverse stakeholders in vegetation habitat planning, management and policies. The southeastern places played an important role in the priority conservation areas for vegetation habitat, and there were more conservation areas located in east of study site than west. As increasing of target levels (ranged 10%–90% percentages of summing amount for vegetation HS index at watershed scale), the spatial priority conservation areas for vegetation habitat gradually extended from the south to the north. The spatial structure of priority conservation areas for vegetation habitat with boundary length effect was more compact than that without boundary length effect. The total priority conservation areas with boundary length effect were approximate to those without boundary length effect, but the total boundary length of former was far less than that of latter. It suggested that integrating boundary length effect to systematic conservation planning of vegetation habitat could produce more aggregated conservation patches and increase connectivity among patches. The total priority conservation areas for vegetation habitat were traded off against total boundary length of reserve networks. It indicated that this tradeoff information could help stakeholder to reasonably allocate investment to maintain reserve network under different target levels. The proposed approach could provide useful information to assess the responses of priority conservation areas for vegetation habitat to different protected targets and boundary length effect, and also guarantee ecosystem sustainability across watershed.

There is a growing call for spatial conservation prioritization of ecosystem services (ESs) models that is both simple and scientifically credible, in order to serve ecological and environmental decision-making processes. Pressure on ecosystems to provide various and conflicting services is immense and likely to increase. Despite increasing attention to the human dimension of conservation projects, a rigorously spatial conservation planning on balancing multiple ESs has not been developed. The impacts and success of spatial conservation planning will be enhanced if the needs of competing and compromising ESs are recognized. We developed such a framework integrating watershed model into spatial conservation prioritization model and illustrated it about competing and compromising ESs in the Teshio River watershed, with the aim of developing a spatial conservation priority ranking map that balances interactive relationships between water yield and sediment retention. The sediment retention was concentrated in southeastern and some northern areas with higher precipitation, more forest lands and steeper slope, but the water yield was concentrated in southwestern and some northern places with agricultural land. The spatial priority conservation ranking map of individual ES is closely related to its spatially distributed pattern. The spatial priority conservation areas for sediment retention in southwest are traded off against those for water yield in southeast, but there are some overlaps on spatial priority conservation areas for sediment retention and water yield in north of Teshio River watershed. There are obvious differences between the spatial priority conservation ranking maps of individual ESs and those of multiple services together. The spatial priority conservation areas for multiple ESs together simultaneously include southeastern, more eastern and some northern places of study watershed, which can balance the conflict existing between sediment retention and water yield. The proposed framework in this study could be applied to similarly structural conservation prioritization problems of other more ESs, which could sustain ecosystem conservation and economic development across watershed.

Ecosystem services (ESs) provide information on the tendency of ecosystems to reach and form a state of equilibrium. The process of ES changes is important in order to identify the climate change-related causes that occur regionally to globally. ES-based management plays an important role in mitigation strategies for the negative impact of global climate change on ecosystem. Therefore, it is necessary to evaluate spatial characteristics and relationships among these multiple services from different spatial scales which could aid in multiple ES sustainable development from local to global scales. In this study, we developed a framework for analyzing the spatial characteristics and interactive relationships of multiple ESs. We analyzed the spatial distributions of six hydrological ESs that are important in the northernmost part of Japan (Teshio River watershed) by using hydrology and nutrient model (Soil and Water Assessment Tool, SWAT) under baseline climate conditions and climate change derived from the global circulation model (GCM). We then explored the spatial characteristic scales of ESs by multiscale analysis (lacunarity estimation) to reveal provision flow and spatial distribution characteristics for hydrological ESs. We observed a strong relationship between the spatial characteristics of land uses and ES provision. The spatial characteristics of individual hydrological ESs were totally different and had different spatial homogeneity and cluster (indicated by initial lacunarity index and lacunarity dimension). The results also showed trade-offs between inorganic nutrient retention (provision ESs) and organic nutrient and sediment retentions (regulating ESs), and synergies between organic nutrient retention and sediment retention under all climate change scenarios. The different stakeholders will take different mitigation programs (e.g., establishing riparian vegetation, planning nutrient management practices, and integrating climate change model into systematic conservation planning of ESs) to avoid negative impacts of climate change on ESs. Application of this proposed framework to study the spatial characteristics and relationships of hydrological ESs under climate change could provide understanding on the impact of climate change on ES changes and solutions to mitigate strategies to cope with those changes in the future.

The arid valley is a unique type of ecological fragile landscape in the Hengduan Mountain Area, China. The boundary of the arid valley is one of the response indicators to mountainous climate change. Based on the meteorological data from 1999 to 2013 and the SPOT remote sensing images in 1999 and 2013 this study explored the response characteristics of the arid valley boundary to regional climate change in the upper reaches of the Min River in the Hengduan Mountains. The results are as follows: (1) During 1999–2013, the temperature, precipitation, and evaporation increased, and the sunshine duration and relative humidity showed decreasing trends at the rates of 0.008 °C/a, 2.25 mm/a, 5.51 mm/a, −8.72 h/a, and −0.19%/a, respectively. Meanwhile, the climate showed the warm-dry tendency in the southern region and the warm-humid tendency in the central and northern areas. (2) On the whole, the arid valley boundary mainly distributed between 1601–3200 m and moved downward to 2428 m at the speed of −0.76 ± 0.26 m/a along with global warming. The descent speeds in different regions showed the same decreasing order as the regional distributions of precipitation and sunshine duration. (3) The arid valley boundary’s displacement in the whole basin had significant negative correlations with current climate change (p < 0.05), as well as with variations of moisture factors. Additionally, with the enhancements of the drought degree and humidity tendency, the variations of temperature, evaporation, and relative humidity, respectively, became the main factors that had significant correlations with the arid valley boundary’s displacement. Therefore, climate change during 1999–2013 shows beneficial effects on the improvement of the arid valley habitat in the upper reaches of the Min River. The study provides a new method and gives basic data for research on climate change.
