Importance Evaluation on Ecosystem Services in Fuping County

本文以河北省保定市阜平县为例,从土壤保持重要性、水源涵养重要性以及生物多样性保护重要性等3个方面分析构建了生态系统服务功能评价指标体系,全面分析了阜平县生态系统服务功能的重要性及其区域规律。结果表明,阜平县的生态用地生态系统服务功能的重要性划分为4个级别,分别为极度重要、高度重要、中度重要以及轻度重要。通过计算可知,生态系统服务功能中度重要及以上级别的生态用地面积是236650 hm2,其比例达到了总面积的93.7%,其中高度重要区和中度重要区所占比较大,极度重要区所占比较小。

This paper taking Fuping County,Baoding City,Hebei Province as an example,analyzed and constructed an evaluation index system of ecosystem services from three aspects,such as the importance of soil conservation,the importance of water conservation and the importance of biodiversity conservation,and comprehensively analyzed the importance of ecosystem services and its regional rules in Fuping County.The results showed that the importance of ecosystem services of ecological land in Fuping County could be divided into four levels:extremely important,highly important,moderately important and mildly important.The calculation indicated that the ecological land area of moderately important ecosystem services and above was 236650 hm2,the proportion reached 93.7%of the total area.Among them,highly important and moderately important areas accounted for a large proportion,while extremely important areas accounted for a small proportion.
