摘　　要：根据浮游动物群落生态特点及群落健康的概念构建浮游动物群落生态健康评价指标体系，确定了各指标健康等级的阈值范围，建立了基于熵权的浮游动物群落生态健康模糊综合评价模型。并以长江口浮游动物群落为例进行案例研究，结果表明2004～2006年春、夏季长江口浮游动物群落均处于不健康状态，与实际情况相符，验证了该模型的可靠性和可行性。The indicator assessment system for the ecological healthy of the zooplankton community was set up based on the ecological characteristics of zooplankton and the concept of community healthy. The range of the indicators healthy standard were given, the en-tropy weight and fuzzy synthetic assessment model was established, and the zooplankton in Yangzi River Estuary was taken as the case to assess its healthy by the model. The results showed the zooplankton in Yangzi River Estuary was in unhealthy state in spring and summer from 2004 to 2006. Thus the model was reliable and feasible.
