Divergent trends of ecosystem status and services in the Hexi Corridor

In terms of ecosystem structure, quality, and service, we have constructed a total 18 characteristic evaluation indicators that could reflect the “state change interaction” analyzed Spatio-temporal in Hexi Corridor from 2000 to 2020. The results show that: 1. improvement service is more obvious areas with better ecological background East. supply regulation services are synergetic. 2. past 2 decades, conditions corridor improved as whole, hot spots for improving quality gradually moved eastward. 3. Ecosystem changes significantly changed quantity relationship services, showing strong spatial heterogeneity. For example, loss natural vegetation central eastern regions good backgrounds has water conservation also enhanced synergy between it service. From perspective coordination characteristics weakened, but performance poor west just opposite. short, typical climate dry land little rain pattern resource shortage not only jointly determine region, bring significant differences greater uncertainties transformation services. Therefore, dryland management protection should be based on detailed differentiated assessment, taking into account regional endowment, giving priority stability increasing
