Abstract

The soil in Yellow River Delta wetland was collected in July 2007.The content of Cu,Zn,Cr and Mn in soil was analyzed and the distribution of heavy metals was studied.The result showed that except Cu,the heavy metals were not significantly accumulated in this area and the content of heavy metals did not harm to the environment and plant.The distribution characteristics of heavy metals were mainly controlled by natural geochemical environment.The contents of soil organic matter,total nitrogen with the content of Cu,Zn,Cr,Mn and between heavy metals had significant correlation(α=0.01,n=36) which indicated the soil organic matter was closely related to the heavy metal elements and the Cu,Zn,Cr,and Mn had similar source and horizontal distribution.
