| Abstract: | Soil environmental quality regionalization of China is significant for soil environmental management. In this paper, the spatial pattern of soil environmental quality of China is analyzed on the basis of data mining, spatial overlay and verification of background values of soil heavy metals, geochemical values of heavy metals and organic pollutant content. The index system of soil environmental quality regionalization is established according to the formation mechanism of regional soil environmental quality. The proposed draft of soil environmental quality regionalization includes 4 first-class regions, 22 second-class regions and 57 third-class regions. The results provide scientific basis for the formulation of soil environmental function regionalization and prevention and control of regional risk in China. |
