摘要:

研究生态系统服务的供需关系有助于科学评估人类对生态系统的依赖程度及区域可持续性,为资源管理与生态保护提供决策依据。科尔沁沙地属于中国北方典型的农牧交错带,生态问题突出,但目前缺乏对该区域生态系统服务供需测算和人地系统可持续性的精细评价。通过构建生态系统服务供给指数(ESSI)和人类需求指数(HMDI)指数,识别了2000—2023年科尔沁沙地生态系统服务供需演化和空间匹配性,基于供需平衡指数评价了人地系统可持续性。结果表明:(1)草地生态系统服务供给在所有土地利用类型中占比最高,供给和调节服务在2005年之前波动较大,之后保持稳定;(2)生态系统服务供给与需求的空间格局基本稳定,需求增长显著区域主要在防风固沙生态功能区外围,功能区内部下降明显;(3)生态系统服务供需存在显著的空间错配现象,其中低供给-高需求占比约29%,集中分布在科尔沁沙地南部和东部片区;(4)大部分地区的人地系统可持续性变化不显著,显著下降区域占比2.55%,显著上升区域占比2.96%;(5)从动态变化视角看,2000—2023年生态系统服务和人类需求之间的协同面积占比(79.94%)远大于权衡占比(20.07%),但是基本都属于负向协同演化(即人类需求和生态供给同步下降),同时功能区的权衡占比要远低于非功能区。

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
