Storm runoff pollution has broad impacts and it is difficult to monitor, control and treat. So the quantitative estimation of pollution load is a key step for its control and management.
暴雨径流污染具有影响面广，监测、控制和处理困难而复杂的特点，其负荷定量化是进行治理与控制的重要基础与中心环节。
Storm water samples collected from an urban road in Xi′an City show that the urban road surface runoff has much greater pollution intensity of SS and COD and possess less biodegradability.
对西安市南二环路雨天路面径流排水进行了连续取样监测，表明城市道路路面径流污染物SS和COD具有很高的污染强度，且生物可降解性较差。
The result shows that the peak of pollutant concentration is ahead of or synchronous with that of runoff, and heavy pollution occurs in initial period of storm runoff.
结果表明：污染物浓度的峰值一般提前或同步于径流量的峰值，初期径流污染较重；
The results show that during storm period, non - point pollution concentration and momentary toss are co - occurence with the peak value of runoff, their relations are very closely.
研究结果表明：暴雨期内，非点源污染物浓度及瞬时流失量与径流峰值几乎同步出现，它们之间存在着非常密切的关系。
For water and soil conservation and water pollution control, it is very important to simulate and predict the yield of sediment and pollutant during storm-runoff.
