摘    要:重金属污染是当今土壤污染中影响面最广、危害最大的环境问题之一。对青海湖典型湿地土壤Cu、Zn、Pb、Cr、Fe、Mn 6种重金属元素的含量及分布特征进行了调查分析。结果表明:青海湖湿地土壤Cu、Zn、Pb、Cr、Fe、Mn 6种重金属元素的平均含量分别为16.34μg/g、46.82μg/g、15.65μg/g、58.49μg/g、14.57mg/g和33.08μg/g;青海湖区南北两岸典型湿地土壤重金属含量存在明显的空间差异。南北两岸样带上表层土壤Cu、Cr、Fe的含量变化均呈"W"形,Zn仅在青海湖北岸样带表现出"W"形,Mn元素含量在400m处为最低点,Pb没有表现出明显的变化特征;Cu、Zn、Pb 3种元素含量呈极显著相关,说明青海湖湿地土壤重金属污染有一定的同源性。

Abstract:Heavy metal pollution in soil is one of the most influential and damaging environmental problems.The contents and distribution of six heavy metal elements including Cu,Zn,Pb,Cr,Fe,Mn in Qinghai Lake wetlands were analyzed.The results showed that the average contents of Cu,Zn,Pb,Cr,Fe,Mn in the wetlands soil were 16.34μg/g,46.82μg/g,15.65μg/g,58.49μg/g,14.57 mg/g,33.08μg/g,respectively.A clear spatial difference in both northern and southern shore wetland of Qinghai Lake was showed.The Cu,Cr,Fe appeared to be in "W"pattern,while the Zn appeared to be"W"only in the north shore,the Mn was the lowest at the 400 m plot;neither in the north shore nor the south shore did the Pb showed any distinctive change.Correlations analysis showed extremely significant positive correlation among Cu,Zn and Pb,indicating that the heavy metal pollutions had definite homology in the Qinghai Lake.
Keywords:Qinghai Lake  Wetlands  Soil  Heavy metal
