| 摘 要： | 由于公路建设,原有土壤被扰动,形成了一种新的人为土—路域土壤。公路建设过程中由于外来土壤的引入、施工机械的碾压,导致土壤质地组成比例、土壤孔隙度、有效土层厚度等发生变化。公路运行过程中,由于汽车尾气排放、轮胎磨损、燃料油泄漏等问题,导致土壤中重金属和有机污染物含量不同程度的增加,造成土壤不同程度的污染。

Impact of Road Construction on the Roadside Soil |

| Abstract: | Because of road construction,the original soil is disturbed,and has formed a new artificial soil-soil road?side. Because of introduction of alien soils,construction machine rolling in the process of road construction,it leads to soil texture and composition ratio,soil porosity,soil effective thickness changes. During operation,because of vehi?cle emissions,tire wear,fuel oil leaks and other problems,this has resulted in an increase in soil with varying de?grees of heavy metals and organic contaminants and different degrees of pollution. |
