    基于生态系统服务供需变化的赤水河流域生态修复分区与策略

    Ecological zoning from the perspective of ecosystem service supply and demand in the Chishui River Basin

    • 摘要: 生态系统服务是连接自然生态系统和社会经济系统的关键桥梁,对经济社会发展和保障人类福祉具有重要意义。从生态系统服务供给与需求平衡开展生态修复分区研究,是新时期因地制宜制定针对性生态保护修复策略和协调区域间发展的重要前提。本文以赤水河流域为研究区,以街道(镇)为评价单元,分析2010-2020年生态系统服务供需变化,基于二者耦合协调程度将409个评价单元划分为高阶耦合、高阶失调、低阶失调和低阶耦合四个类型,结合各区供需变化量提出了生态保育型、重点修复型、生态连通型和价值转化型等赤水河流域差异化生态保护修复分区策略,为山水林田湖草一体化生态保护修复提供了科学依据。

       

      Abstract: Ecosystem services works as key bridge connecting natural ecosystems and socio-economic systems, and are of great significance to sustainable development as well as gain of human well-being. Research on the zoning for ecological protection and restoration from the balance of ecosystem services supply and demand is an essential prerequisite for compiling targeted ecological protection and restoration strategies and coordinating inter-regional development in the new era. We here selected Chishui River Basin as the study area with the evaluation unit down to the level of streets or towns. Changes of ecosystem service supply and demand between 2010 and 2020 years were calculated. The total of 409 evaluation units were divided into four types including high-order coupling, high-order disorder, low-order disorder and low-order coupling based on the degree of coupling and coordination. Together with changes in supply and demand, we here proposed the differentiated ecological protection and restoration zoning strategies for the Chishui River Basin including ecological conservation type, key restoration type, ecological connectivity type and value transformation type. The finding is expected to provide a scientific basis for the integrated ecological protection and restoration.
