摘　　要： 采用三级模糊综合评价法对鄱阳湖水质进行综合评价,研究利用水质指标构建二级因素集,利用测站代表月构建三级因素集,经过二级、三级评价分别得到测站各代表月与全年的水质综合评价结果,给予鄱阳湖月、年水质变化的客观描述。以2008年为例的研究结果表明:就全年而言,除赣江南支、瓢山、鄱阳、信江东支局部水域为二、三类水外,鄱阳湖大部分地区总体上属于一类。就月水质变化而言,除了修河口、渚溪口、星子、蛤蟆石、蚌湖一带水质以Ⅰ类为主,且年内变化较为稳定外,其它水域水质变化相对较大,同时较差水质多出现在枯水期。 Based on three fuzzy Comprehensive evaluation method,the Poyang Lake water quality was evaluated,two-level and three-level factor set were built by water quality indicators and typical months of stations.After two-level and three-level comprehensive evaluation,typical months and year water quality evaluation results of stations were obtained.A Case Study in the 2008 results show that for the full year,In addition to local waters of the southern branch of Ganjiang,Piaoshsan,Poyang and the east branch of Xinjiang were the Class-Ⅱand Ⅲ of water,most parts of the Poyang Lake belong to classⅠof water;for the typical months,In addition to estuary of Xiu river,Zhuxikou,Xingzi,Hamashi,Bang lake area were ClassⅠmostly and water quality was stable during the year,other bodies of water have larger changes in water quality and poor water quality often in the dry season.
