| 摘 要： | 目的]了解潍坊市土壤重金属污染现状及其在空间上的分布规律,为该区土壤重金属污染防治和农业生产的合理安排提供指导。方法]在土壤重金属污染调查的基础上,以ArcGIS为操作平台,采用地质积累指数分析潍坊市土壤重金属污染状况,并绘制空间分布图。结果]潍坊市大部分地区土壤重金属未产生污染,但在某些地区镍的污染等级达到3级;8种重金属污染程度依次为:HgNiZnCrPbCdCuAs;土壤中Cd,Ni,Pb,Hg受土壤质地影响,Cd,Ni,Pb易在砂土中富集,Hg易在黏土中富集;重金属元素浓度与土壤pH值相关性较差;Hg的浓度与土壤有机质有着非常显著的正相关关系(p0.01);Ni污染存在着复合现象;重金属元素中,Cu,Cr,Ni在空间的分布主要集中于青州—临朐—昌乐交界处和安丘—诸城交界处。结论]土壤重金属污染分布与人类活动有关,应加强地区交界处的环境管理力度。

| 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 different 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. |
