Abstract Human activities are becoming increasingly diverse and disordered, especially in arid areas, which affect ecosystem services more obviously. Conversely, ecosystem services also impose certain constraints on human. In this paper, we employed the model of ecosystem service value (ESV) assessment and grey relational degree, to reveal the spatiotemporal variation characteristics of ecosystem service value in Xinjiang and its interaction with human activities. The results showed that, during 2000–2015 the value of food production services (FPV) showed an upward trend, while the value of climate regulation services (CRV), gas regulation services (GRV), raw material production services (RMPV) and recreation services (RSV) showed a downward trend. The value of hydrological regulation services (HRV) showed a trend of first decreasing and then rising, while the value of waste disposal services (WDV) showed a trend of first increasing, then decreasing and then increasing. Spatial change showed that the services value of Kashi and Aksu Prefecture declined significantly, while Altay and Tacheng Prefecture increased significantly. In Xinjiang, human activities had a strong interaction with ecosystem services. Agricultural activities (0.989) and social development activities (0.844) had the greatest impact on changes in ecosystem services, especially agricultural water consumption (0.984) and total population at year-end (0.965). Hydrological regulation services (0.8179) had the greatest restriction on social and economic development. Combining the spatiotemporal changes in ecosystem service value and their variation with human activities are significant to formulate ecological policy and coordinate sustainable development.
