摘要:
通过对西禹高速合阳段路域土壤的调查和分析，并和未受人为干扰的自然土壤进行比较，研究了公路路域土壤的成因、特点及其限制因子，并总结出如下特点：（1）土壤物理性质差；（2）有机质和养分贫乏，pH值普遍偏高；（3）土壤成分复杂，侵入体多；（4）有效土层有限，植物扎根受限；（5）土壤重金属污染因素增多。
Abstract:
In order to expound the characteristic and the formation of road soil,this paper took an existing road area soil as a typical case study,which lies in Xi-yu expressway Heyang section.Compared with the undisturbed natural soils,investigated and analyzed the expressway road area soil,and summarized the formation and characteristic and its limit factors as the following: (1) Worsening of soil physical properties is a general characteristic.(2) Soil organic matter and nutrient were scanty,and the pH value of road soil were higher than local natural soil.It has the trend to be the alkaline soil.(3) The soil component was quite complex,too much invasive matter were intermingled.(4) The valid soil depth was limited and its higher rigidity made it’s difficult for plant to take root.(5) Because of the continuing exposing to the exhaust gas,it had more likelihood to be polluted by heavy metals.
