【摘要】 本文以沪宁高速公路为例,采用地统计学方法对沪宁高速公路两侧土壤中Pb、Cd、Cr、Zn、Cu 5种重金属有效态含量的空间分布特征进行分析。结果表明,沪宁高速两侧土壤中Pb、Cd、Cr、Zn、Cu有效态含量均整体呈现随公路距离增加而先增后减的趋势,5种重金属有效态含量在公路两侧的空间分布特征不尽相同。有效态Pb、Zn含量的空间分布受公路交通污染的影响较大,而有效态Cd、Cr和Cu则主要受土壤重金属背景值以及理化性质的影响。更多还原

【Abstract】 The spatial distribution of available contents of Pb,Cd,Cr,Zn and Cu contamination in the soil alongside Shanghai-Nanjing Expressway was analyzed by the geostastical method.The result indicated that the available contents of Pb,Cd,Cr,Zn and Cu in the soil on both sides of the expressway increase to a peak firstly along with the distance of the road and then gradually showed downtrend.But the spatial distributions of such five kinds of heavy metal were not identical.The traffic pollution has great influence on the spatial distribution of available contents of Pb and Zn contamination.,otherwise the available contents of Pb and Zn was influenced buy the background value of heavy metal and physical and chemical properties of the soil alongside the expressway.更多还原
