摘　　要：本文针对平原河网地区湖泊特点与水生态系统状况,从物理形态结构、水文特征、水体质量状况、水生生物及底栖生物5个方面构建了平原河网地区湖泊水生态系统评价指标体系。综合运用层次分析法和熵权法确定指标权重,依据升降半梯形函数确定隶属度,建立基于模糊理论的生态系统评价模型,并将该评价指标体系和评价模型应用于太湖,进行了太湖水生态系统评价。According to the ecological condition of lakes in plain river network, water ecological evaluation index system was established in this paper, considering five respects： physical form structure, hydrologic characteristics, water quality status, aquatic organisms and benthonic realm. Analytic hierarchy process and entropy method were applied to determine the weight of each evaluation index. Lifting semi-ladder of membership function was applied to determine membership. Evaluation model of water ecosystem was established based on the fuzzy theory. The evaluation index system and the evaluation model were applied to Taihu Lake to evaluate its water ecosystem situation.
