| 摘 要： | 地表径流属于非点源污染，地表径流的产生取决于复杂的降雨过程，径流中污染物浓度，径流深度，产流面积是地表径流污染负荷的３大要素，该文对上海郊的４种地表径流进行了调查，并在污染源评价的基础上与市郊非点源污染总量进行了比较。结果表明，上海市郊进入水全的污染负荷，ＣＯＤｃｒ约为６２６３４．７ｔ／ａ，总氮为６２８８．２ｔ／ａ，总磷为１２４４．６ｔ／ａ，此结果说明地表径流是上海市郊仅次于畜禽类尿的重要非点污染

| Abstract: | Surface runoffs is a non-point source pollution produced by a complicated raining process. Runoffs depth, pollutant concentration and area are three elements of surface runoffs pollution load. Investigations of pollution load of 4 surface runoffs have been conducted, and compared with total non-point pollution load in Shanghai suburbs on the basis of pollution sources assessment. The total amount of pollutants such as CODcr, TN, TP discharged from surface runoffs into water body in Shanghai suburbs were 62634.7t/a, 6288.2t/a and 1244.6t/a respectively. Surface runoffs was an important non-point pollution source in Shanghai suburbs next to animal husbandry excrements. |
