摘要

以沪宁高速公路两侧土壤为研究对象,按不同的土地利用方式(有林带和无林带)采集土壤样品,研究了交通对土壤重金属污染的影响及公路绿色通道建设对重金属污染的防护作用。结果表明:沪宁高速公路土壤重金属Cu、Pb、Zn含量在不同土层的分布未发现明显规律性;土壤重金属Cu、Pb、Zn的含量随公路垂直距离的增加并非呈简单的线性负相关;绿色通道建设对土壤重金属污染有明显减弱的作用,对防治公路土壤重金属污染效果是明显的,但绿色通道的结构、宽度、配置方式对防护功能影响很大。

Abstract

In this study, we investigated the soil heavy metal pollution and protective effect of greenway construction along ShanghaiNanjing highway.Soil samples were taken on both sides of the highway under different landuse conditions (with or without greenway). Results showed that there were no significant changes in heavy metal (Cu, Pb and Zn) contents along soil depths. No negative linear correlations between heavy metal (Cu, Pb and Zn) contents and the vertical distance from highway were found.The greenway construction had significant protective effect on soil heavy metal pollution. However, the structure, width, and configuration mode of the greenway had great influence on the protection function from soil heavy metal pollution.
