Therefore, analyzing main driving factors of formation and changing of ecosystem services that can support sustainable development in this region. In this research, the ecosystem services evaluation system which combined value ranking and ecosystem services function intensity matrix was constructed. Combing three key drive factors coupling, driving intensity of each factor was assessed, and then completed driving and migration analysis of hot and cold spots of ecosystem services. The results showed that the ecosystem services increased from 2000 to 2010. However, the hotspots during this period were mostly transformed into cold spots during 2010-2015, while the whole ecosystem service benefits showed a slight decline in the past 15 years. Because of urbanization process, the layout of construction area tended to be more compact. The human disturbance indexes of three periods were increasing in both northern and southern Xinjiang Province, thus the ecosystem services driving by human disturbance index were all decreasing. The driving intensity of vegetation coverage was low in south Xinjiang province due to the extremely limit. Precipitation accounted for high contribution of total ecosystem services, but it can also make the service efficiency fluctuate greatly. Compared with the southern Xinjiang, the northern Xinjiang region ecosystem showed stronger resistance and integrity under external interference, so as to achieve relatively high efficient output of ecosystem services. The spatiotemporal change analysis of ecosystem service under the effect of key driving factors is helpful to understand the cause of local ecological environment changes and guide for local ecological environment. %R %U http://cjarrp.com/zgnyzyyqh/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
