城市快速路侧有无绿化路段土壤重金属污染风险对比研究
A comparative study on the risk of heavy metal pollution in the soil of the urban expressway with and without greening trees
城市土壤重金属污染来源繁杂,对城市居民的健康及植物的生长均带来不良影响。本研究以新疆首府乌鲁木齐市典型城市道路——河滩快速路侧有无绿化带土壤为研究对象,分析了乌鲁木齐市快速路侧有无绿化带土壤土壤重金属浓度分布特征,初步评价了土壤污染状况,为城市绿化带的合理建设与营造提供理论依据。其主要结论如下,(1)本文研究区内有绿化带与无绿化带路侧土壤重金属含量均值随着离道路的增加而显著降低的,说明城市道路对土壤重金属浓度均值有一定的干扰、增加作用。(2)有绿…查看全部>>
There are many sources of heavy metal pollution in urban soil,which have adverse effects on the health of urban residents and the growth of plants.In this study,taking the soil of the River Beach Expressway,a typical urban road in Urumqi,the capital of Xinjiang,as the research object,the distribution of heavy metal concentrations in the soil of the green belt on the side of the Expressway in Urumqi city is analyzed,the soil pollution status is preliminarily …查看全部>>
