Ecological Risk Assessment of Soil in Rapid Urbanization Area by Risk Regionalization

Abstract

Rapid urbanization is a major source of environmental risk in soil. In this study, we developed a method for the ecological risk assessment in rapid urbanization area, which was set up based on potential ecological risk assessment and risk regionalization. The 10 heavy metals were extracted from the Soil Baseline Study of Tianjin, and the four risk levels were built according to the adjusted valuation criteria in the method. The results showed that the level of ecological risk was closely related to the degree of Soil pollution in in Rapid Urbanization Area. 1
