摘要
From the perspective of ecological geochemistry,this paper systematically studies the spatial distribution features of the heavy metals in the soils from Kangding city of Sichuan Province.Furthermore,the paper analyzes the sources of heavy metal pollutants.On the basis of the fuzzy evaluation,the paper finally builds the comprehensive evaluation model of soil quality.The model will help to classify the pollution and to determine the degree of pollution.
