中文摘要：
物元分析是用来处理在某些条件下用通常的方法无法解释的不相容问题的一种分析方法。文章以扎龙湿地水体中重金属污染评估为例,针对8个监测断面的5种重金属指标（锰、锌、铜、铬、砷）污染现状,用熵权法来确定指标的权重,构建模糊物元模型,用以实现水质的等级评价和监测样点排序,结果表明：扎龙湿地不同监测位点污染程度从重到轻递减顺序如下：东升水库〉林甸排污口〉核心区仙鹤湖〉翁海排干〉克钦湖〉龙湖〉特勒桥〉龙安桥。湿地水源入口和核心区污染重金属污染严重,湿地的功能分区未能起到实质效果,湿地核心区未得到合理的保护。
英文摘要：
The matter element analysis theory is the way for dealing with some problems which can not reach the aim in some special conditions.On the basis of principle of matter element analysis,heavy metals in water quality of Zhalong Wetland system were studied.Results showed that pollution levels of different monitoring sites in the Wetlands ranked from heavy to light as Dongsheng Reservoir,Lindian Drainage,Crane Lake,Wenghai Drainage,Kachin Lake,Long Lake,Tele Bridge and Long Ann Bridge.The inlet and core area were serious polluted with heavy metals.Functioning of the Wetland played no part in the core area protection.
