The contents of Pb, Cd, Cr, Cu, Zn and Mn in the wetland soil were determined, and the degree of soil heavy metal pollution was estimated by single-factor pollution index, root-mean-square comprehensive pollution index and geo-accumulation pollution index methods. The results showed that the wetland in the sampling range was seriously polluted by heavy metals, mainly by heavy metal Cd, while the effects from other heavy metals were relatively less.展开更多
