A Fuzzy Cluster Mathematic Model of City Topsoil Heavy Metal Pollution

By analyzing the propagation characteristics of heavy metal pollutants, a fuzzy clustering model is established. Based on the topography, residential areas, factories, roads, etc. as well as the index Muller, we get the degree of heavy metals pollution and a evaluation on comprehensive pollution, and we found that the weight of pollution of each category and the index of the comprehensive pollution of heavy metals on the region by using fuzzy clustering and fuzzy AHP
