摘要
开展区域生态系统服务功能动态区划,对生态系统服务功能的分区管理具有重要的指导价值。本文介绍了生态系统服务功能区划的方法——生态系统服务功能动态区划系统(SIZES)。该方法包括生态系统服务功能多层次表征、位序矩阵生成、核心生态系统服务功能空间辨识和动态区划边界生成四个模块,它们能实现生态系统服务功能动态区划边界的生成。其中,生态系统服务功能多层次表征模块和动态区划边界生成模块是主要模块,而构建生态系统服务功能表征指标体系和生成区划单元是该方法的关键所在。利用SIZES将锡林郭勒盟划分为6个生态系统服务功能区,科学合理地解释了该区生态系统服务功能空间分异规律,为指导该区生态系统服务功能分区管理,提供了具有时空特性的决策参考信息。
Maintenance of a sustainable ecosystem services is critical for human future. Ecosystem services degra- dation, however, is a common phenomenon around the world which leads to poor ecosystem services. In order to pro- tect ecosystem services, it needs to implement ecosystem services management within different functional zones. Methods for ecosystem services division are the key to generate and represent functional zones, and studies on zon- ing ecosystem services can guide regional eco-management. This paper introduces spatial fuzzy clustering analysis embedded in System for Identifying and Zoning Ecosystem Services （SIZES）. SIZES contains four main modules： multi-level indicators of ecosystem services characterizing module, importance rank of ecosystem services generating module, the core ecosystem services spatially identifying module, and zoning boundary of ecosystem services delimi- tating module. This approach can iteratively generate ecological delimitation boundary after inputting influencing factors of the ecosystem services and the core ecosystem services is extracted using factor analysis and then the boundaries of the ecosystem services zones are delimitated. Application of SIZES approach in Xilingol League shows that six functional zones scientifically and rationally explain the ecosystem services, and the result provides valuable spatial and temporal decision-making information for ecosystem services management.
