Spatio-temporal variations of ecosystem service value and its spatial heterogeneity mechanism in the economic belt around Tarim
Based on the three periods of land use data of the economic belt around Tarim in 1990,2005 and 2020,the characteristics of land use change and spatial and temporal changes of ecosystem service value(ESV)were analyzed,and the spatial differentiation mechanism of ESV in the economic belt around Tarim was explored with the support of geographical detector tools.The results showed that from 1990 to 2020,the area of grassland,water area and forest land in the study area all decreased,while the area of construction land,cultivated land and unused land all increased.There was a significant wave-like decrease in ESV from the peripheral mountain-ous areas to the central basin.The spatial distribution pattern of ESV cold and hot spots was characterized by"a circular hot spot dis-persion on the outside and a patchy cold spot aggregation on the inside".The main driving factors of the spatial differentiation of ESV in the economic belt around Tarim were the proportion of unused land,meteorological factors and elevation.The interaction between vari-ous factors was enhanced,and the explanatory power of natural factors was higher than that of socio-economic factors.
