摘　　要：初期雨水和初期冲刷是城市雨水径流污染控制中两个不同的重要问题,然而,目前国内对这两个问题的认识还普遍存在明显的局限性。基于1999年以来对城市雨水径流污染规律的研究,并结合国内外学者的研究成果,对初期冲刷现象及其描述方法、污染物积累输送规律等进行分析,明确提出研究、讨论初期冲刷问题首先应区分两种不同的典型条件;归纳了初期冲刷的主要影响因素,并进一步对国内外一些学者讨论初期雨水和初期冲刷问题时存在的矛盾与困惑进行剖析,澄清初期雨水与初期冲刷的不同概念,为把握其基本规律、深入研究城市径流污染规律、有针对性地制定有效控制措施提供理论和科学依据。Initial rainwater and first flush are two important issues in urban stormwater runoff pol- lution control. However, clear limitations exist in awareness of the two issues in China. Based on the monitored data and investigations in Beijing since 1999, as well as investigations by many researchers around the world, first flush concept, its descriptive methods and regularity of pollutant accumulation and transportation are analyzed. It is pointed out that two representative conditions should be distinguished separately in the discussion on first flush. The major influential factors on first flush and the main reasons for controversy on initial rainwater and first flush are discussed. The different concepts of initial rainwater and first flush are clarified to provide a theoretical and scientific basis for grasping their basic regularities, research on urban runoff pollution and development of pertinent control measures.
