针对深圳市光明新区城区径流，采用SCS径流曲线模型对其SS、COD、TN及TP等污染负荷进行了估算。结果表明，光明新区城区径流污染负荷中， SS、COD、TN、TP的污染负荷量分别为18527.8、11023.81、197.29和91.58 t ，其中COD的排放负荷已超出其收纳水体茅洲河环境容量6.0倍， COD和SS的年输出系数值也明显高出同类城市， SS和COD为该地区降雨径流中的主要污染物。

With regard to the urban runoff located in Guangming New District of Shenzhen City, SCS runoff curve model was adopted to estimate pollution load such as SS,COD,TN and TP. Results showed that pollution load amount of SS,COD,TN and TP in the runoff were 18527.8 tons, 11023.81 tons, 197.29 tons and 91.58 tons respectively. The discharge load of COD exceeded the environmental capacity of Maozhou River into which the runoff flows by 6 times. Annual output coefficients of COD and SS were significantly higher than those of other similar cities. Moreover, SS and COD were the main pollutants in the stormwater runoff of this region.
