摘  要:
土壤的污染特别是重金属污染问题,是发展必须面临和需要解决的问题之一。以大沽河流域农田表层土壤为研究对象,采用栅格形采样,共采集大沽河流域土壤样本124份。采用化学方法测量5种重金属(As、Cd、Cr、Hg、Pb)含量,并基于山东及全国的土壤背景值数据,进行统计分析、相关分析和比较分析。采用样条差值法,基于此数据使用Arc GIS,实现5种重金属元素的空间分布专题制图。对重金属分布特性与人类活动和流域特征进行分析,指出污染严重的地区。重金属污染的区域分布特征,可以为新一轮大沽河流域的土壤综合控制和产业规划提供参考。

摘  要:
Especially heavy metal contaminated soil pollution problems, which is one of the problems of development must face and need to be addressed. Farmland soil surface Dagu watershed was studied using a grid-shaped sample, collected 124 soil samples Dagu river basin. Using chemical methods for measuring the five heavy metals(As, Cd, Cr, Hg, Pb) content,based in Shandong and the country's soil background value data, statistical analysis, correlation analysis and comparative analysis were conducted. Using the spline differential method, five kinds of spatial distribution of heavy metals in thematic mapping was achieved which based on this data using Arc GIS. Characteristics of heavy metal distribution characteristics and human activities and basin were analyzed, which pointed out serious polluted areas. The regional distribution of heavy metal pollution provided a reference for integrated control and industrial planning a new round of Dagu river basin soil.
