Abstract

Evaluation of geological environment in urban soil is an effective way to indicate the quality of the urban environment. In a city, after an acquisition of sufficient samples of topsoil concentrations of heavy metals information, we can conduct a numerical analysis of the city comprehensively and explore the locations of pollution source of each heavy metal. Then we apply the fuzzy recognition method to plot eight kinds of spatial distribution of heavy metal elements in the urban areas and their degrees of pollution. According to the national environmental quality standards for soil, the method can be used to determine the pollution levels for each sample point and different levels of pollution in life zones, industrial parks, mountains, trunk roads and park green areas. Through the analysis of the propagation features of heavy metal pollutants, we can establish a concentration-displacement offset model to determine the location of each source.
