首先利用matlab绘出八种重金属元素在某城区的分布图，并运用模糊数学知识分别建立隶属函数，层次分析法得到各金属元素的权重，并用权重修正后的内梅罗污染指数法加以修正，经归一化、加权得到整个体系污染程度的综合评价，并指出污染的主要原因，最后对模型进行了检验与分析。

Firstly, a distribution map of eight heavy metal elements in a certain city region is shown by use of matlab, respectively membership functions are established by use of the the knowledge of fuzzy mathematics. The weight of the metal elements is obtained according to analytic hierarchy method. Then the weights are modified by using the Nemerow pollution index. The comprehensive evaluation of the degree of pollution is gotten in the entire system after normalized and weighted, the major causes of pollution are pointed out. Finally the model is tested and analysed.
