摘　　要：为研究不同雨型条件下南方典型小流域城市的降雨径流特征,以深圳市观澜河流域为研究对象,通过对研究区域连续进行为期半年的降雨监测,从中选择常见的3种基本雨型(双峰型、前峰型、后峰型)条件进行水体中常规污染物的浓度分析,并为典型南方降雨径流控制措施的制定提供理论指导。得出结论如下:①双峰型降雨条件下,研究区域内不同功能区典型污染物浓度存在单一峰值,峰值时段位于降雨初期;②前峰型降雨条件下,典型南方小流域城市不同功能区典型污染物浓度存在2个峰值,前期峰值时段位于降雨初期,后期峰值时段位于降雨10 min左右;③后峰型降雨条件下,典型南方小流域城市不同功能区典型污染物浓度存在2个峰值,前期峰值时段位于降雨初期,后期峰值时段位于降雨60 min左右。To study the characteristics of rainfall runoff in typical small basin cities in southern China under different rain patterns,the Guanlan River basin in Shenzhen was taken as the research object.Through real-time continuous rainfall monitoring in the study area for half a year,the concentration of conventional pollutants in water was analyzed by selecting three kinds of common basic rainfall patterns(bimodal rainfall,advanced rainfall and delayed rainfall),which provides theoretical guidance for the formulation of typical rainfall runoff control measures in southern China.The following conclusions are as follows:(1)Under the condition of bimodal rainfall,there is a single peak in concentration of typical pollutants in different functional areas in the study area,and the peak period is in the early stage of rainfall.(2)Under the condition of advanced rainfall,there are two peaks in the concentration of typical pollutants in different functional areas of typical southern small basin cities.The peak period in the early stage is in the early stage of rainfall,and the peak period in the later stage is about 10 minutes of rainfall.(3)Under the condition of delayed rainfall,there were two peaks in the concentration of typical pollutants in different functional areas of typical southern small basin cities.The peak period in the early stage is in the early stage of rainfall,and the peak period in the later stage is about 60 minutes of rainfall.
