水的生态服务功能内涵与评价方法初探

A preliminarystudy on connotation and assessment approach of ecosystem service function of water

从水的生态服务功能的机理出发,深入剖析了其内涵与水的两层次生态服务结构,并在此基础上构建评价水的生态服务功能的指标体系,介绍了评价流域水的生态服务功能的主要方法;最后提出了维系流域水的生态服务功能主要思路与手段,为水的生态服务功能研究提供了新思路与新方法。

Based on the mechanism of the ecosystem service function of water, its connotation and the double functional layers of the ecosystem service structure of water are deeply analyzed herein. On the basis of this, the index system for assessing the eco- system service function of water is built up, and then the main approaches for assessing the ecosystem service function of the wa- ter within a river basin are introduced as well. Finally, the major concepts and means for maintaining the ecosystem service func- tion of the water within a river basin are put forward, so as to provide some new concepts and approaches for the study made on the ecosystem service function of water.
