摘要：流域生态系统具有物质循环、能量循环、群落代谢等服务功能，随着社会的发展，城市化进
程加快，人类活动等干扰因素的影响，流域生态系统的健康遭受严重威胁。在对太湖流域（江

苏）水生态系统状况深入调查研究的基础上，以生物多样性维持功能、重要生境维持功能、水环
境支持功能和重要物种保护功能4类功能为目标，构建化学、生物与生境复合指标体系，通过评

价指标的计算及赋值，对整个太湖流域（江苏）49个水生态环境功能分区，从高到低划分为Ⅰ级~
Ⅳ级4个等级，最终形成太湖流域（江苏）生态功能综合评价方法。

Abstract:The watershed ecosystem has the service functions of material circulation, energy circulation, commu⁃
nity metabolism, etc. With the development of society, the acceleration of urbanization and the influence of human ac⁃
tivities, the health of watershed ecosystem is seriously threatened. Therefore, based on the in-depth investigation and
study of the water ecosystem status of Taihu Lake Basin (Jiangsu), this study aims to build a composite index system of
ߌ࣢აؿᅚ࿐ඌ௹़
chemistry, biology and habitat to comprehensively evaluate the health status of water ecosystem in Taihu Lake Basin
(Jiangsu) with the functions of biodiversity maintenance, important habitat maintenance, water environment support
and important species protection. Based on calculation and assignment of evaluation indexes, the 49 regions of Lake
Taihu Basin (Jiangsu) were divided into four grade levels(Ⅰ ~ Ⅳ) to evaluate their ecological functions and the com⁃
prehensive evaluation method of ecological function was formed.
Key words:Taihu Lake Basin; Watershed ecosystem; Ecological function; Comprehensive index system
