中文摘要：

选取2002年和2007年分别代表洪湖湿地恢复前后的年份,从湿地生态系统健康度的角度来反映其恢复效果.根据洪湖湿地自身的特点,选取了湿地生态系统特征、功能整合和社会经济环境3个亚类24个指标建立了洪湖湿地生态健康评价指标体系,采用模糊综合评判模型对洪湖湿地2002年和2007年的生态健康状况进行了评价.研究结果表明：洪湖湿地2002年和2007年的生态系统健康度分别为0.5240和0.6369,健康状态由＂一般病态＂转化为＂一般健康＂,湿地恢复工程取得了显著的效果;2007年洪湖湿地健康指标中表现为＂疾病＂状态的指标为优势性植物覆盖率、水质净化功能、环保投资指数和化肥施用强度,这些因素成为限制生态系统健康的关键因素.

英文摘要：

In order to evaluate the ecological restoration effects of Honghu Lake wetland,we compared the ecosystem health of Honghu Lake wetland before（in 2002）and after（in 2007）the wetland restoration project.Based on the characteristic of Honghu Lake wetlands,an index system to evaluate the healthy condition of the wetland ecosystem has been designed,which includes three secondary indexes-characteristic of wetland ecosystem,function integrate and social-ecosystem,and 24indexes totally.The results show that the ecosystem health indexes of Honghu wetland are 0.524 0in 2002and 0.636 9in 2007respectively,which indicate that the ecosystem health index ranges from morbidity before the Honghu Lake wetland protection and restoration demonstration project（HLWPRDP）to middle health after the HLWPRDP.The results also indicate that the main limit factors to wetland health are the coverage of dominant species,the function to purity wastewater,the index of environment protect and the intensity of fertilizer usage.
