Revealing trade-off and synergistic relationships among ecosystem services plays a key role in ensuring stable for long-term development. It is the crucial precondition realizing watershed protection high-quality The variations land use during 1990–2020 are investigated by taking typical areas returning farmland to forests as an example. spatiotemporal distributions of six services, namely carbon storage, water yield, net primary productivity (NPP), soil conservation, habitat quality, forest recreation quantified InVEST model statistical data. We also uncover spatial difference Loess Plateau, located northern Shaanxi, with hot spot analysis probe correlations services. results show that: (1) decreased dramatically. On contrary, orchards increased significantly. (2) During same period, storage quality increased, NPP, initially declined, but subsequently rose higher values than that 1990. All these southeastern part research area surpass those found northwest.

A Novel Framework for Integrally Evaluating the Impacts of Climate Change and Human Activities on Water Yield Services from Both Local and Global Perspectives

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(16), P. 3008 - 3008

Published: Aug. 16, 2024

With global climate change and irrational human activities, regional water resource conflicts are becoming more pronounced. The availability of in watersheds can be indicated by the yield. Exploring factors that influence yield is crucial responding to protecting resource. Previous research on influencing has frequently adopted a macro-level perspective, which failed reflect mechanisms changes at local scale adequately. Therefore, this study proposes novel framework for integrally evaluating impacts activities services from both perspectives. Taking Ganzhou City, source Ganjiang River, as an example, results show following: (1) City had largest 1307.29 mm 2016, lowest was only 375.32 2011. spatial distribution pattern mainly affected surface environment, high-value regions area were predominantly located urban areas with flat terrain. (2) At scale, where contribute than 80% accounted 25% area. In comparison, impact 0.95%. contribution rate significantly greater change. (3) simulation four scenarios contributed (>98%) yield, higher (<2%).

Water yield and purification are important aspects of water ecosystem services, achieving a balanced development the two is necessary for aquatic ecosystems. Using InVEST model, spatiotemporal variations regional services in Shanxi, China, from 2000 to 2020 were analyzed. Three future scenarios (natural development, urban ecological protection) assessed 2030 using PLUS model. The results showed that 2000–2020, Shanxi Province terms space was generally low middle northwest high southeast, it affected by land-use change climatic change. From 2020, changed 78.8 mm.

With the intensification of global climate change and environmental degradation, goals carbon peaking neutrality have become crucial strategies for promoting sustainable development in various countries. However, most studies on ecological environment quality (EEQ) focus urban areas, with limited attention to county-level analyses, particularly regarding complex interactions between climate, topography, human activities. This study aims address this gap by investigating spatiotemporal evolution multidimensional driving factors EEQ 107 counties Shaanxi Province, China. Using Google Earth Engine (GEE) platform MODIS imagery, along methods such as Remote Sensing Ecological Index (RSEI), Hurst exponent, GeoDetector, analyzed evolutionary characteristics mechanisms EEQ, explored improvement management different types county within framework dual goals. The results indicate that: 1) From 2000 2020, overall Province showed a fluctuating upward trend, improving from moderate level good level, although some experienced slight degradation 2010 2020. 2) spatial distribution displayed “low-high-low-high” gradient north south, indicating superior conditions southern central-northern counties, while northern regions faced significant challenges. 3) future trend is expected be one continuous improvement, must paid ongoing risks highly urbanized areas. 4) differentiation primarily driven influenced synergistic effects multiple factors.
