摘　　要：基于当量因子法估算2000—2020年南疆地区生态系统服务价值(Ecosystem services value,ESV),应用生态-经济协调度(Ecological-economic harmony,EEH)模型从县域尺度分析南疆地区生态-经济发展协调水平及其空间分布特征,最后通过生态贡献率模型揭示各县域ESV变化主要贡献因子,并结合其ESV损益状况和生态-经济协调水平进行差异化的可持续发展分区。结果表明:(1)2000—2020年南疆地区ESV整体呈先上升后下降趋势,总量缩减167.99×10^(8)元;草地和水体的ESV占总量的70%以上,单项ESV调节服务(57.1%)>支持服务(27.5%)>文化服务(10.0%)>供给服务(5.4%);草地和农田是多数ESV实现增益(减损)县域的主导地类。(2)2000—2020年南疆地区37个县域ESV均有不同程度减损,ESV实现增益县域共计9个;约80%的县域为生态-经济初始恶化区,其余县域表现为生态-经济协调稳定状态。(3)南疆地区整体呈轻度生态-经济不协调状态,少数生态-经济协调稳定县域主要分布于南疆中、东部地区。综合分析将南疆县域划分为林草生态-经济不可持续区、农田生态-经济不可持续区、水体生态-经济不可持续区、林草生态-经济持续稳定区和农田生态-经济持续稳定区5种类型。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 167.99×10^(8) 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.
