城市表层土壤重金属污染模型建立与评价
Modeling and Evaluation on Heavy Metal Pollution of Surface Soil in a City
摘要
Abstract
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.关键词
