为了解析华南地区道路径流污染特性及其影响因素，对华南地区典型城市深圳市道路进行了4场降雨的径流样品采集及分析。结果显示道路径流水质劣于地表水4类环境质量标准，说明道路径流已经成为影响城市水环境质量的重要威胁。同时研究发现初期冲刷效应受到降雨类型和污染物种类的双重影响，因此在针对道路径流处理设施特别是初雨截流装置的设计时，需要同时考虑降雨类型与污染物种类。另外，建议华南地区的初雨截流量为3～5 mm的初期降雨。这些研究结果能为有效的道路径流处理设施设计提供有用的建议。

In order to have an in-depth understanding of road runoff characteristics and the linkages to their influential factors this paper investigates the road runoff quality in a city of South China Shenzhen.Four rainfall events with different characteristics are monitored on a typical urban road.It is noted that the road runoff quality is worse than Grade Ⅳ of environmental quality standards for surface water.This means that the road runoff has posed a serious risk to water environment health. Furthermore the research outcomes indicate that first flush highly varies with rainfall patterns and pollutant species.This means that for road runoff treatment design rainfall patterns as well as pollutant species should be taken into consideration and this is particularly essential to design first flush capturing devices. Additionally the threshold of an initial 3 to 5 mm rainfall depth is suggested to the first flush capturing device design.These results provide useful suggestions to the effective road runoff treatment design.
