Spatial–Temporal Evolution of Ecosystem Service Value in Yunnan Based on Land Use

Exploring the changes in ecosystem service value (ESV) caused by land use transition is important for regional ecological protection. According to data from 2000 2020, alterations and ESV Yunnan over past 20 years were calculated analyzed. At same time, spatial autocorrelation analysis was established analyze relationships of 16 states cities. The results show that cultivated land, grassland unused are on a decreasing trend, while forest water body built-up an increasing with largest change land. total supply, gas regulation, climate environmental purification hydrological regulation being highest individual services. Spatially, showed high levels northwest, southwest east, low northeast, west central parts. it shows positive correlation weakening trend. It dominated high–high cluster low–low cluster. services have greater impact region, main contributing sensitive factor.
