"The 14th five-year plan"of Green traffic development planning proposes the overall concept of coordinated development be-tween transportation infrastructure and ecological environment,where the prevention and control of transportation pollution is a major theme.Effectively controlling source pollution and weakening subsequent treatment facilities can help achieve the"double carbon"goal.The protection of water ecology is a key and difficult point in the prevention and control of transportation pollution.Due to the high pollution in-tensity of rainwater runoff in the early stage of road surface,as well as the potential harm of sudden hazardous chemical transportation leak-age accidents,the special attention has been paid to the impact on the ecological environment and surface water bodies.By analyzing and ex-ploring the characteristics of road pollution,understanding the causes and main components of road runoff pollution,mastering the character-istics of sudden and catastrophic accidents in hazardous chemical transportation,sorting and distinguishing water environment sensitive road sections,and combining with road drainage systems,a detailed analysis is conducted on the selection of technical parameters for road drain-age pollution prevention and control design in water environment sensitive road sections,and corresponding technical measures and sugges-tions are proposed for reference and reference by peers.
