摘要: 持续而剧烈的人类活动已经对水生态系统的健康和安全造成了严重的影响。对流域的水生态功能进行甄别,合理划分其生态功能区,并按不同功能合理管理水资源,成为协调经济发展和水生态保护的关键因素之一。本文通过分析流域水生态功能分区的概念、内涵、特征以及区划方法的系统发展,提出了水生态功能分区的一般划分原则、划分指标和方法,为建立和完善我国流域水生态功能分区的理论和方法,提供了基础信息。

Abstract: Sustained and intensive human activities have serious impact on the he alth and security of aquatic ecosystems. It is one of the keys to coordinate eco nomic development and ecological protection at watershed scale by discriminating aquatic ecological function, establishing aquatic ecological function regions, and rationally administrating water resources based on different functions. Thro ugh the analysis of the development in the concept, definition, characteristics, and approach of aquatic ecological function region at watershed scale (AEFRWS), this paper proposed the principles, indicators, and methods of AEFRWS regionali zation, and provided basic information for the establishment and improvement of the theories and approaches of AEFRWS in China.
