| Abstract: | Environmental pollution in Kunming City has been studied geochemically. This paper, using geochemical data of bedrock and soil, investigates primary environment and secondary environment of this area as well as their relation ship, discusses assessment indices for soil pollution (pollution indices), divi des this area into subareas with different degrees of pollution and, combined with biologic data, analyzes the influence of pollution on ecologic environment. The data obtained are of practical value to environmental geology and agri cultural geology. |
