太湖流域水生态功能分区

水生态功能分区是进行流域现代水资源管理的必然要求,是面向水质目标管理污染控制单元划分的基础。在发生学原则、区内相似性原则以及共轭性原则等相关原则的指导下,采用因素分析法对太湖流域一级水生态功能区进行划分,通过对流域DEM和气候、土壤等相关分区指标的比较分析,认为地形是太湖流域一级水生态功能分区的主导指标,分区结果主要包括西部丘陵水生态区和东部平原水生态区,并对两个一级水生态功能区的特征进行了阐述;在此基础上,对太湖流域水生态功能分区体系即分区等级体系、方法体系和指标体系进行了探讨。

Delineation of aquatic ecoregions in Taihu lake basin

Aquatic ecoregions are increasingly used as a spatial unit for planning and environmental management,and they have become an indispensable condition for environmental assessment and modern water resource management,and also are the basis of delineating the polluted control units oriented on the water equality targets management in basin scale. In this paper,factor analysis approach was selected and used to delineate the level I aquatic ecoregions in the Taihu lake basin under the guidance of the aquatic eco...
