“…The decreasing runoff will not only inevitably affect water demand from the water diversion project but also influence urban water supplies, agricultural irrigation, and shipping traffic in the middle and lower reaches of the Hanjiang River, changing the erosion and siltation conditions in the river and reducing the self-regulating capacity of the river due to hydrological variations [33,64]. Studies have shown that the spatial distribution of crops across the landscape is subject to local climatic conditions (e.g., rainfall) [34]. Stakeholders are concerned about the efficacy of easing the negative stress from climate variability through land-use change [59].…”

“…The Hanjiang River Basin is the largest tributary of the Yangtze River, and the Upper Hanjiang River (UHR) is the water source area of the Middle Route Project of the South-to-North Water Diversion in China [33,34]. The river extends over a length of 652 km through the west to east of the UHRB, covering 6.02 × 10 4 km 2 and accounting for 39.76% of the Hanjiang River drainage area.…”

“…The river extends over a length of 652 km through the west to east of the UHRB, covering 6.02 × 10 4 km 2 and accounting for 39.76% of the Hanjiang River drainage area. The UHRB is a typical natural ecological zone [34] located in the center of China (Figure 1a) and is a high-value basin for socio-economic activity, biodiversity conservation, and ecological sustainability, both at the watershed and national scales. The northern end of the UHRB is bordered by the Qinling Mountain and the south is bordered by the Daba-Micang mountains.…”

“…The ecological quality in the UHRB has been gradually enhanced by the implementation of the "Grain for Green" project and the Ecological Construction of Protection Forestry in the upstream reaches of the Yangtze River [26]. The resulting revegetation facilitated a significant increase in soil and water ecosystem services [34]. The annual mean SC in the UHRB was 439.72 t hm −2 yr −1 and the annual SC was slightly enhanced (p > 0.05), ranging across the study area, accounting for 91.79% (Figure 2b) under current climatic conditions (between 2000 and 2015).…”

Climate change can have critical impacts on ecosystem services (ESs) and their inter-relationships, especially for water-related services. However, there has been little work done on characterizing the current and future changes in these services and their inter-relationships under a changing climate. Based on the revised universal soil loss equation (RUSLE), the soil conservation service curve number model (SCS-CN), and the improved stochastic weather-generator-based statistical downscaled global climate models (GCMs), we examined two important water-related services, namely, the soil conservation (SC) service and the flood mitigation (FM) service, and their inter-relationship under baseline and future climate scenarios (Representative Concentration Pathways (RCPs) 4.5 and 8.5). We took the Upper Hanjiang River Basin (UHRB), which is the core water source area of the China’s South-to-North Water Diversion Project (S–NWDP), as an illustration. The findings revealed that (1) the SC and FM services will both decrease under the two climate scenarios examined; (2) the SC and FM services showed a significant synergistic inter-relationship and the synergy will be improved by 16.48% and 2.95% under RCP 4.5 and RCP 8.5, respectively, which provides an opportunity for management optimization; (3) the ecological degradation in the UHRB will likely have serious consequences for the middle and lower reaches of the Hanjiang river basin, and therefore impact the actual economic benefits of the S–NWDP. This study points to the necessity for understanding the dynamic changes and inter-relationships of ecosystem services under future climate change and provides information regarding the consequences of climate change, which is useful for policy and infrastructure investment.

“…Ecosystems provide multiple water-related services to human beings, such as freshwater supply, water quality purification, surface water regulation, mitigating flood in rain season and sustaining water flow in the dry season [1,2]. However, with the intensification of human activities and climate warming, the water resources crisis is becoming more and more serious, making it increasingly challenging to maintain ecosystems for sustainable services [3,4].…”

Water provision (WP) is an important service of the terrestrial ecosystem, which contributes to water availability for consumptive use and in situ water supply, sustains the production or flows of multiple ecosystem services (ES). Spatially explicit mapping of WP is critical for incorporating the ES concept into the decision-making processes of land-use and ecological conservation planning. Traditionally, regional complexes hydrological process models were simplified and used for mapping WP of the ecosystem at broad scales, but this approach is significantly limited by data accessibility and difficulty validating the results. To fill the gap, an NPP-based composite indicator model that simulates WP by multiplying NPP and its variations with the soil infiltration capacity factor, annual precipitation and the slope of the land surface is proposed in this paper. These parameters are chosen to map WP because they are closely related to hydrological processes. The model results were validated using observed runoff data of the eleven river basins in China. We then applied this approach to analyze the spatiotemporal changes of WP in China from 2000 to 2013. The results show that: (1) the average value of WP was lowest in the Northwest Arid Area ecoregions while the highest value of WP was in the South China ecoregion. (2) The linear trend of WP in the Loess Plateau and Hengduan Mountains ecoregions were increased while decreased in the other nine ecoregions. (3) The WP in the north of the Qinghai-Tibet Plateau presented a significant decrease trend mostly because the land cover change (e.g., grassland convert into dessert) and decreasing precipitation; the decreasing of the WP in Yunan-Guizhou Plateau are because the farmland convert into settlement land and the significant decrease of precipitation and significantly increase of temperature; the significant increase of the WP in Northeast China are because the increasing of forest and farmland, the grassland and wetland convert into farmland and forest, and the significant decrease of temperature and increase of precipitation; Although the increase of precipitation has played an important role in promoting WP, the significant increase of WP in the Loess Plateau was mainly due to the farmland convert into forest and grassland ecosystem types. The indicator explored by this research is benefiting for revealing the variations of WP under different land-use change and climate change, and informed the decision-making process of land-use policy or conservation planning at data-scarce regions or broaden spatial scales.

Understanding how multiple ecosystem services interact, how trade-offs emerge, and how interactions among ecosystem services may change after the Grain-for-Green-Program (GFGP) and is critical for managing multiple ecosystem services.Here, we conducted a spatiotemporal approach to quantify the impact of large-scale afforestation on four key ecosystem services (i.e., crop production, soil conservation, carbon sequestration, and water conservation). We observed that three satellite datasets (i.e., GIMMS-LAI3g, GIMMS-NDVI3g, and NDVI-ESTARFM) time-series show a slightly improved and significantly improved trends, and crop production, carbon sequestration, soil conservation, and water conservation have improved after the implementation of GFGP. Simultaneously, almost 49% of the low levels and 58% of the high levels for all four of the ecosystem services considered changed after the implementation of GFGP. The results also show that relationships among ecosystem services have shifted from a trade-off in 1988 and 1999 to an apparent synergistic relationship in 2011.We conclude that GFGP is a successful programme for addressing trade-offs between services. Our study provides experiential support for largescale restoration programme in humid area around the World.
