摘　　要：为更好地保护公路沿线水体环境,对公路运营产生的沿线水资源影响进行系统分析,认为公路运营可能影响路域水文水系,路面径流的主要污染物为SS和COD,使用融雪剂会引起周边水体氯离子升高,沿线设施污水达标排放率和中水回用率有待提高。结合公路运营期水环境保护技术的研究进展,归纳提出:径流净化技术向功能多元化方向发展,除很好地实现径流净化基本功能外,生态边沟和调节池与人工湿地串联技术具有一定的景观美化效果,生态种植槽能将净化后的雨水储存,待缺水时再利用,径流监控与应急处理系统可实现危化品泄露事故应急功能;使用环境友好型融雪剂能有效降低对路面基础设施的腐蚀,减轻对路域生态环境的破坏;在沿线设施污水处理领域,人工湿地和土壤渗滤技术在南方地区具有推广价值,组合处理技术在北方地区具有广阔的发展空间。For better protecting water environment along highway, the impact of highway operation on water resources was systematically analyzed. It is considered that highway operation will affect hydrological water system and underground water. The main contaminant of road runoff is SS and COD, snow melt agent applying will cause increase of chloride concentration in surrounding waters. The roadside facilities effectiveness in terms of sewage discharge standard and reclaimed water reuse need to be improved. According to the research advance of water environment protection technology during road operation process, it is proposed that （1） Runoff purification technology should be developed as a multiple functions to achieve basic runoff purification function. Besides, the combination of ecological ditches and regulating pools with the constructed wetland would benefit the landscape beautification. Ecological planting tank could storage the purified rainwater, which the storage water could be applied during the lack of rain seasons. Runoff monitor and emergency treatment system could deal with leakage accidents of hazardous chemical leakage. （2） Using environmental friendly snow-melting agent can effectively reduce the corrosion from agent toward road surface facilities, decrease the impact on roadside environment. （3） In the field of sewage treatment facilities along highway, constructed wetlands and soil infiltration technologies have promotional value in southern areas, and the combination treatment technologies can be promoted in northern areas.
