摘要
Abstract
According to the investigation of soil heavy metal contents,As,Cd,Cr,Cu,Hg,Ni,Pb and Zn, in Baihe villiage of Cangxi County, the environmental quality of these metal contents were evaluated by the methods of single pollution index and synthetic pollution index. The results have indicated that the soil environmental quality of the research district is according to the standard of Soil Environmental Quality Class Two, which means the soil quality is preferable and meets the basic requirements for crops. Among these factors, the main factor is the content of Cd, which is over the standard of Soil Environmental Quality Class One but below Class Two. There are two reasons found, the first one is caused by soil parent material and the second one is caused by human activities.关键词
