摘　　要：选取京台高速(编号G3)山东段和国道309(编号G309)山东段路域土壤进行采样分析,测定主要重金属的质量分数,根据土壤环境质量标准,确定污染土壤的重金属种类,并对土壤受污染的程度进行评价。结果表明:公路路域重金属污染现在还不是很严重,还没有到治理的程度,现在要采取预防措施;公路两侧土壤中的重金属质量分数随距公路路基距离的远近而不同,规律各异;公路陆域土壤中的重金属来源多样,如含铅汽油的使用、轮胎磨损、润滑油的使用、汽车尾气等。The soil of Shandong section of Beijing-Taipei Expressway(G3) and Shandong section of National Highway 309(G309) was selected for sampling and analysis. The mass fraction of main heavy metals was measured.According to the soil environmental quality standard, the types of heavy metals in polluted soil were determined and the degree of soil pollution was evaluated. The results showed that the heavy metal pollution in the road area was not very serious and did not yet reached the degree of treatment, and now preventive measures should be taken;the heavy metal mass fraction in the soil on both sides of the road varied with the distance from the road subgrade, with different laws;the heavy metal sources in the soil on the road area were diverse, such as the use of leaded gasoline, tire wear, the use of lubricating oil, automobile exhaust and so on.
