摘　　要：通过对西昌邛海滨湖公路5个不同路段在旱季和雨季降雨期间的有效采样,分析其路面径流的污染特征。结果表明,旱季SS和TN污染贡献率较大,分别为51.206%和24.008%;雨季的SS和COD污染贡献率较大,分别为40.559%和22.058%;5个不同路段的路面径流污染程度均超过邛海湖泊功能的Ⅱ类水质要求,旱季和雨季的污染物浓度存在一定的差异,可能与不同路段的车流量、降雨强度、路面清扫程度以及自然气候等因素密切相关。本文结合其污染因素探讨有效的控制措施,并提出建议。In this paper,water samples of road runoff are collected in five different road sections of Qionghai Lakeside Road during the dry season and rainy season.The pollution index are evaluated by comprehensive index method based on factor analysis.The variance contribution rates in dry season are 51.206% and 24.008% respectively,while the variance contribution rates in rainy season are 40.559% and 22.058% respectively.According to the comprehensive evaluation,it is concluded that the water quality of road runoff in all of the five different sections have exceeded the standard of GraveⅡ quality for Qionghai Lake though there is certain difference in dry and rainy seasons in terms of the contaminant concentration which may be related to the traffic volume,rainfall intensity and degree of cleaning as well as climate etc.In the paper the effective control measures and suggestions are proposed based on the pollution factors.
