摘要
随着公路里程的日益增加和公路网的加密,公路交通已成为公路两侧土壤重金属污染的重要来源。中国人均耕地面积较少,公路两侧仍存在着大量的农田,种植着不同的农作物。研究表明,公路交通已对公路两侧的农田土壤和农作物造成不同程度的污染,对农产品的质量和安全产生较大的威胁。该文系统阐述了公路沿线农田土壤和农作物的重金属污染现状,以及二者之间的关系,深入分析了影响公路沿线土壤重金属空间分布的因素,对公路沿线农田重金属污染的研究方向提出展望,以期为路侧农田土壤重金属的污染防治提供思路与方向。
With the increase in highway mileage and the development of the highway network,highway traffic has become a major source of heavy metal contamination in the soil on both sides of the highway.Due to the small amount of arable land per capita in China,there is still a lot of farmland and various crops on both sides of the road.Research showed that highway traffic had caused different degrees of pollution to farmland and crops on both sides of the highway,which posed a great threat to the quality and safety of agricultural products.In this paper,the status of heavy metal pollution in farmland soil and crops along the highway and the relationship between them were systematically reviewed,and the factors affecting the spatial distribution of heavy metals in soil along the highsway were thoroughly analyzed.Finally,the perspective of the research direction of heavy metal pollution in farmland along the highway was proposed,to provide ideas and directions for the prevention and control of heavy metal pollution in farmland soil along the highway.
