A Stydy on Distribution of Soil Heavy Metal Pollution in Weifang City Based on Geography Information System
摘要
Abstract
[Objective] The concentration and distribution of heavy metal pollution in Weifang City were studied in order to guide the agricultural production.[Methods] As,Cd,Cr,Cu,Hg,Ni,Pb and Zn in 235 soil samples were monitored in Weifang City.And the geo-accumulation index of heavy metal pollution in dif ferent soil types were calculated.[Results] Results showed that the polluted degree of all heavy metals was different.Its average order was:Hg＞Ni＞Zn＞Cr＞Pb＞Cd＞Cu＞As.The geo-accumulation index of Ni was the highest in some regions.Soil organic matter were related with some heavy metals,but pH was not connected with all heavy metals.There existed obvious combined pollution of Ni.Cu,Cr,Ni mainly concentrated in two borders,one of which was the border of Qingzhou,Linqu and Changle area,and the other was on the border of Anqiu and Zhucheng area.[Conclusion] The distribution of heavy metal pollution in soil was associated with human activities,the environmental management of the administrant region boundary should be strengthened.关键词
