| 摘 要： | 采用事件平均浓度（EMC）和M（V）曲线初期冲刷效应判识方法,对2011年4月北京市中心城区和远郊区县降雨径流污染特征进行分析.结果表明,受城郊环境差异影响,径流污染物种类、浓度和初期冲刷效应存在明显分异,城区COD、TP、TN污染物浓度低于郊区,氨氮浓度高于郊区;城区径流存在初期冲刷效应,郊区无明显初期冲刷效应.

| Abstract: | The event mean concentration （EMC） and M （V） curve method of judging first flush effect were used to analyze Beijing center city and remote suburb district runoff pollution characteristics on April,2011.The results show that,under the urban-suburb environment difference effect,runoff pollutants,concentration and first flush effect have major personality differences.COD,TP,TN pollutant concentration of the urban runoff is lower than the suburb; ammonia concentration is higher than the suburb runoff.First flush effect exists in the urban runoff;the suburb has no obvious first flush effect. |

| Keywords: | Urban-suburb gradient Urban surface runoff Non-point pollution First flush effect |
