Abstract:

Accurately identifying the spatial characteristics of ecosystem service supply and demand, as well as delineating ecological management zones, is crucial for guiding regional ecosystem management and restoration efforts. This study focuses on the overall ecosystem of northwest China, quantifying the spatial matching of water production, carbon sequestration, and food services from 2000 to 2022 using the water-energy-food nexus as a framework. Ecological management zones are delineated based on the surplus and sustainable characteristics that align supply with demand. The results indicate that (1) The spatial matching of supply and demand for ecosystem services in northwest China varies. Specifically, the supply and demand for water production and food services either fluctuate or remain stable, whereas the demand for carbon sequestration services increases. This rise in demand, coupled with declining supply and demand-supply ratios, leads to a gradual imbalance in matching supply and demand. (2) Food production services are primarily sustainable, whereas water production and carbon sequestration services tend to be unsustainable. (3) Classification and management of ecological zones that consider both ecological and human well-being are necessary, with the aim of enhancing the supply of ecosystem services. The findings of this study provide valuable scientific insights into the rational allocation of basic resources and the precise management of ecosystem services in northwest China.

Key words: ecosystem services, supply-demand match, ecological management zoning, northwest China
