构建锡林郭勒盟生态系统服务功能评价指标体系,利用1 km栅格成分数据,采用因子分析法在空间上辨识各种生态系统服务功能及其重要性;然后在1 km×1 km栅格水平上开展模糊聚类分析,在空间上标定、辨识生态系统服务功能一致性图斑单元,并在此基础上开展生态系统服务功能空间分区研究。研究表明,利用因子分析法提取出的锡林郭勒盟的核心生态系统服务功能重要性排序为文化功能、调节功能、支持功能和供给功能。根据生态系统服务功能的一致性特征及空间模糊聚类法,在锡林郭勒盟划分出6个生态分区,对于制订该区生态系统管理决策有重要的指导价值。
The evaluation index system of the ecosystem service functions in Xilingol League was constructed.Using the data of 1 km grid composition,each ecosystem service function and its importance were distinguished in the space by using factor analysis method.Then the fuzzy clustering analysis was made at the level of 1 km×1 km grid to calibrate and identify the map spot units with consistent ecosystem service functions.On this basis,the spatial zoning of ecosystem service functions was studied.The research results showed that the importance order of the core ecosystem service functions in Xilingol League extracted by factor analysis method were as follows: cultural function,regulation function,support function and supply function.According to the consistence characteristics of ecosystem service functions and the spatial fuzzy clustering method,Xilingol League was divided into 6 ecological subareas,which had important guiding values for formulating the decisions of the ecosystem management in this area.
