摘　　要：从湖泊水环境理论出发,以灌区的草型湖泊乌梁素海为研究对象,用基于监测样本信息的主成分分析确定权重的模糊综合评价方法,从水质、富营养状况和水生生态3方面对2006-2008年6月份乌梁素海各功能区水环境指标的均值进行综合评价,定量地评价出各功能区的水质级别。综合评价的结果为:农业用水区的水质为4.416级,景观娱乐用水区的水质为3.635级,渔业用水区的水质3.122级,混合区的水质4.762级,得出乌梁素海大部分水体已处于富营养状态。Starting from theory of the lake water environment,It takes Wuliangsuhai Lake which is grass type lake as study object in arid area.The method of fuzzy synthetic evaluation,basing on monitoring sample information of various functional areas,determining the weight of principle component analysis.The water environment state of wuliangsuhai lake in June from 2006 to2008 is evaluated from three aspects-water quality,eutrophication and water zoology quality,confirming the level of water environment.Furthermore,we can assess the various functional areas＇s water quality by comprehensive evaluation for wuliangsuhai Lake,The conclution is that the degree of agricultural water areas,entertainment landsape,fishery water areas and mixing zone respectively is 4.416,3.635,3.122 and 4.762,in addition,most of areas of Wuliangsuhai Lake were in the state of eutrophication.
