Abstract:

Ecosystem services are closely linked to sustainable human development. Studying the supply and demand characteristics of regional ecosystem services and comprehending their spatial matching status are essential prerequisites for achieving the efficient allocation of ecological resources and promoting regional ecological security. The water production, carbon sequestration, and food services of the Shule River Basin in the Gansu Province of China were all examined on the basis of multisource data and with the assistance of the InVEST model as well as the ArcGIS and GeoDA software. The following are the results of this study: (1) There are discrepancies between different regions and ecosystem services; except for water production services, the supply of other ecosystem services in the Shule River Basin is more than the demand. (2) The supply-demand ratio of comprehensive services in the Shule River Basin is 0.063, and the supply-demand ratios of different ecosystem services are carbon sequestration services (0.1854)>food services (0.0078)>water production services (-0.0043). (3) Water production and carbon sequestration service spaces are mainly based on low-high-type and high-low-type spatial dislocation, respectively, whereas food service spaces are primarily based on low-low-type spatial matching, among which the spatial mismatch of water production services is the most severe.
