摘　　要：为研究长江中游底泥的质量现状,选取干流和湖泊点采集底泥样品,对主要指标(重金属、总P、总N及有机质)进行测试分析,采用NOAA泥沙质量标准和背景值质量标准对底泥质量进行模糊综合评价。从总体上看,中游干流底泥质量较好,而湖泊点底泥质量不容乐观。中游干流八处采样点中七处底泥质量良好,城陵矶莲花塘底泥质量最差,对水体环境存在一定有害风险;中游五处湖泊采样点中监利天鹅洲白暨豚保护区和洪湖深水区两处底泥质量良好,洞庭湖和武汉东湖质量一般,而梁子湖底泥质量较差。为维护长江的水生生态环境,应有效控制进入长江(尤其是邻近湖泊)的点源及面源污染。Sediment was sampled from the main stream and adjacent lakes of the middle Yangtze River and the important indices （heavy metals, total P, total N and organic matter） were tested to research the status of sediment quality. The sediment quality was evaluated by comprehensive fuzzy method according to NOAA Sediment Quality Guidelines and Sediment Background Approach （SBA）. In general, the sediment quality of the main stream middle Yangtze River is good, while that of lakes is somehow gloomy. Among the eight sampling sites of the main stream, sediment quality of seven sites is fine, while that of Lianhuatang in Chenglingji reach is bad, and is the worst of the eight sites, and has some potential negative impacts on aquatic environment. Among five lakes in the middle Yangtze River,sediment quality in Chinese River Dolphin Reserve in Tian＇ E Zhou, Jianli County is fine, that in Dongting Lake and Donghu Lake is ok, while that in Liangzi lake is bad. To maintain the aquatic environment of the Yangtze River （especially the adjacent lakes）, the point and surface pollution into the Yangtze River should be effectively controlled.
