摘　　要：采用现场连续取样,在雨天某一时段对西安至临潼高速公路路面径流排水进行了监测.结果表明,高速公路路面排水具有较高的污染强度,污染物以SS和COD为主,且生物可降解性较差.水质参数SS、COD、总Pb、总Zn之间存在较好的线性相关关系.分析探讨了路面径流污染物排放规律及其对河流水质的影响.With on-site continuous sampling, drainage water from expressway runoff of Xi'an-Lintong expressway was monitored in a period of a wet weather. The results show that the expressway runoff has greater pollution intensity and the main pollutants are SS and COD with rather low biodegradability. There are better linear relations among the water quality parameter SS, COD, total lab and total Zn. The rule of pollutant discharge of the highway runoff and its impact on water quality of the river were discussed.
