Spatial-Temporal Variation and Mechanisms Causing Spatial Differentiation of Ecosystem Services in Ecologically Fragile Regions Based on Value Evaluation: A Case Study of Western Jilin, China

The concept of Ecosystem Service Value (ESV) is indispensable when balancing the need for economic development and ecological protection, because it can clarify assets values provided by a region. study spatio-temporal variation ESV in ecologically fragile regions helpful attempting to restore regional function. Taking area Western Jilin as an example, this paper analyzes spatial distribution spatial-temporal evolution characteristics integrated ecosystem service value (IESV) constructing IESV model. drivers differentiation mechanisms controlling interaction between various factors are examined using geographical detector technique. results showed that areas high with services were mainly distributed protected areas, there has been downward trend past 23 years. Moreover, explanatory ability NDVI (Normalized Difference Vegetation Index) was strongest any natural considered. Among socio-economic factors, power human activity index (HAI) greatest. Additionally, exhibits synergistic enhancement, which affects degree IESV. result joint action activities factors. This provide scientific basis optimization ecosystems security Jilin.
