Abstract:

Understanding ecosystem service (ES) supply-demand relationships is crucial for scientifically evaluating human-ecosystem interdependencies and regional sustainability, thereby informing resource management and ecological conservation strategies. As a representative agro-pastoral ecotone in northern China, Horqin Sandy Land faces severe ecological challenges, yet comprehensive assessments of ES flows and human-earth system sustainability remain scarce. This study developed Ecosystem Service Supply (ESSI) and Human Demand (HMDI) indices to quantify ES evolution and spatial matching patterns (2000-2023), evaluating sustainability through supply-demand balance diagnostics. Key findings reveal: (1) Grasslands contributed most significantly to ES provision, with supply services and regulation services stabilizing post-2005 after earlier fluctuations; (2) Spatially consistent patterns featured accelerated demand growth along functional zone peripheries, contrasting with declining internal supply; (3) Pronounced spatial mismatches emerged, particularly low-supply/high-demand zones (29%) concentrated in southern-eastern sectors; (4) Limited sustainability transitions occurred (2.55% significant degradation vs. 2.96% improvement); (5) Synergistic areas dominated (79.94%), characterized predominantly by negative synergies (concurrent ES-demand declines), while trade-offs were minimized within functional zones.

Key words: human-earth system, ecosystem service supply-demand dynamics, conflict and coordination, sustainability assessment, Horqin Sandy Land
