基于多重生态系统服务能力指数的生态空间优先级识别

快速城市化地区空间极为有限,识别具有关键景观生态功能的生态源及其保护优先次序,对提升区域多重生态系统服务水平和可持续发展有重要意义.通过构建的耦合模型,评价了生态空间的多重生态系统服务能力指数;基于该指数进行的聚类分析结果将研究区域的生态空间划分为6个优先级.优先级越高表明它的功能重要性越大,维持或提升服务的难度越小,...

Identifying and Setting of Natural Space Priorities Based on Multi-Ecosystem Services Capacity Index

In the case of limited spaces in the rapidly urbanized areas, it is of great significance to identify ecological sources with key landscape ecological functions and their protection priorities for enhancing the level of regional multi-ecosystem services and sustainable development. In this paper, the multi-ecosystem service capability index (MESC index) of each natural space were evaluated by the constructed coupling model. The results of clustering analysis based on the index divided the natural spaces into six priority grades. The higher the priority grade of natural space is, the more important its function is, and the less difficult it is to maintain or enhance the services, which also means that this natural space should be identified as an important ecological source and brought into the ecological network in the first place. The method based on MESC index evaluation proposed here provided a clear and repeatable framework and useful planning reference information for the hierarchical management of natural spaces.
