Heavy Metal Pollution in City Topsoil Fuzzy Clustering Model
Keyword(s):
It is a hot research project to find the heavy metal distribution in city topsoil and the level of pollution in city function region. Based on two dimension theory of Weiersreas, the eight heavy metal distribution is obtained, and the number of function region is calculated. Considering longitude and latitude of the polluted region, the high concentration distribution of heavy metals in area and the surrounding area is get. The pollution domain is found by using reverse Markov chain. The heavy metal pollution source is calculated from Gaussian diffusion model.
