摘要
以典型铅锌矿为研究对象,就矿山开采对周围土壤造成的影响进行了调查,分析了矿区土壤污染的机理及成因。通过建立重金属污染迁移试验模型,并采用偏最小二乘法(PLS)建立迁移能力线性回归曲线方程得出了主要污染元素镉(Cd)、铅(Pb)、锌(Zn)的迁移特性。
Taken typical Pb-Zn mine as the research object, the influence of mineral exploring on the surround- ing soil is investigated. The mechanism and causes of minefield soil pollution are analyzed. Through establishing mi- gration experimental model of heavy metal pollution, the migration characteristics of main pollution elements such as Cd （cadmium）, Pb （lead）, Zn （zinc） are obtained by adopting the partial least squares （PLS） approach and establis- hing the linear regression curve equation migration.
