【 摘 要 】

This paper aims to study three main metal mining areas in Yunnan Province, to summarize and analyze the heavy metal pollution situation in each mining area, and to assess the ecological risk of the mining areas. The results showed that heavy metal pollution existed in different regions of the three mining areas with pollution elements of Cd, As, Cu, Pb, Zn. Risk level, besides Zhen Yuan mining area (class C), for the other two areas was class D, with Beichang mining area in Lanping as the most serious polluted mining area.
