Abstract:

This paper estimated the ecosystem service value (ESV) of the southern region of Xinjiang, China from 2000 to 2020 using the equivalent factor method. The ecological economic harmony model was applied to analyze the coordination level and spatial distribution characteristics of ecological economic development in the southern region of Xinjiang at the county level. Finally, the ecological contribution rate model was used to reveal the main contribution factors of ESV changes in each county and differentiate sustainable development zones on the basis of their ESV profit and loss status and ecological economic coordination level. The results showed that from 2000 to 2020, the overall ESV in the southern region of Xinjiang initially increased and then decreased, with a total reduction of 167.99×108 Yuan. Grassland and water ESV accounted for over 70% of the total, with single ESV regulation services (57.1%)>support services (27.5%)>cultural services (10.0%)>supply services (5.4%). Grassland and farmland were the dominant land types for most ESV gains (losses) in counties. (2) From 2000 to 2020, the ESVs in 37 counties in southern Xinjiang decreased to varying degrees, with 9 counties achieving ESV gains. About 80% of these counties were areas with initial ecological economic deterioration, whereas the remaining counties exhibited a state of ecological economic coordination and stability. (3) The overall ecological and economic imbalance was mild in the southern region of Xinjiang, and a few counties with stable ecological and economic coordination were mainly distributed in the central and eastern regions of southern Xinjiang. Through comprehensive analysis, the counties of southern Xinjiang were divided into five types: forest and grass ecological, economic unsustainable zone; farmland ecological, economic unsustainable zone; water ecological, economic unsustainable zone; forest and grass ecological, economic sustainable, stable zone; and farmland ecological, economic sustainable, stable zone.

Key words: ecosystem service value, ecological-economic harmony, EEH model, sustainable development zoning
