摘　　要：研究针对公路绿化景观土壤中的重金属污染,采用断面法对公路绿化景观土壤取样,分析土壤中的Pb、Cu、Zn、Cr、Ni、Cd重金属空间分布特征和含量,研究重金属之间的相关性,研究重金属的来源是否相同。采用地累积指数和分级标准对公路绿化景观土壤进行潜在的生态风险评价,并分析污染程度和污染空间的分布特征。开展公路绿化景观土壤重金属污染含量分析和生态评价,分析重金属在土壤中的含量和迁移路径,可为公路绿化土壤和农业生产的合理分布及污染防治提供基础数据和科学依据,具有重要的社会意义和环境意义。The study focuses on the heavy metal pollution in the soil of highway greening landscape.The cross-sectional method is used to sample the soil of highway greening landscape,analyze the spatial distribution characteristics and content of Pb,Cu,Zn,Cr,Ni,Cd heavy metals in the soil,study the correlation between heavy metals,and investigate whether the sources of heavy metals are the same.This paper uses land accumulation index and grading standards to evaluate the potential ecological risk of highway greening landscape soil,and analyze its pollution degree and distribution characteristics of pollution space.An analysis and ecological evaluation of heavy metal pollution content in soil for highway greening landscape was conducted to study the content and migration path of heavy metals in soil.The results can provide basic data and scientific basis for the rational distribution and pollution prevention of highway greening soil and agricultural production.It has important social and environmental significance.
