Analysis of Spatial-Temporal Differentiation and Influencing Factors of Ecosystem Services in Resource-Based Cities in Semiarid Regions

The spatial-temporal differentiation characteristics and driving mechanisms of ecosystem services are great significance for optimizing the pattern land spatial protection realizing regional sustainable development. Existing studies seldom consider segmental influence mechanism various influencing factors on different levels service value (ESV). Therefore, this paper analyzes temporal evolution ESV in semiarid regions through an improved evaluation model. panel quantile regression (SPQR) model was introduced to explore relationship between types intervals. results showed following: (1) changes Baotou City from 2000 2018 tended be stable, but intensified. aggregation feature low-ESV region is significant gradually expanding. (2) Precipitation dominant factor increasing each interval, temperature had a negative impact area. (3) Higher use integrity accelerates decline surrounding areas built-up areas. high-ESV area more sensitive intensity human activity. direction activities should effectively controlled, structure comprehensive optimized enhance function ecosystems. This research provides new thinking ecological restoration zoning territorial planning development resource-based cities.
