摘要
文章结合河南省巩义市的实例,对县域小尺度生态功能区划分的方法和指标选取进行实际应用的探讨。巩义市生态功能区划采用2级分区(生态区和生态功能区)的等级体系。其中,生态功能区的划分采用定量与定性相结合的方法,定量分析中选取了形成生态系统特征、影响生态服务功能的14个特征因子进行聚类分析,在此基础上,再采用主导标志法进行区域划分。最后提出巩义市4个生态区和8个生态功能区的二级生态功能区划方案。
The aim of this paper is to discuss the method and indexes of regionalization of the county ecological function, that is demonstrated in a case study in the Gongyi City（ 1 041 km^2 ）, which is one of the fastest growing areas in central region of China. Two levels units（physical eco- region and eco- function region）were utilized for the regionalization. Eco -function region were divided by a comprehensive method of combing quantitative analyses, taking cluster analyses, with qualitative analyses, taking dominant indication. Fourteen characteristic factors forming features of ecosystem and influencing ecological service function were selected as indexes in cluster analyses. To assess the importance of ecological service function, eco- function regions were taken into account to determine boundary lines of delineation by the method of dominant indication. The Gongyi City can be divided into 4 physical eco - region and 8 eco - function region divisions.
