摘要： 选取常熟金泾塘地区典型农用地为研究对象,通过人工降雨研究不同降雨条件下径流污染物的输出特征,并分析径流污染对河水污染的贡献。结果表明:小强度降雨径流初期污染物输出浓度最大,而高强度降雨径流污染物输出最大浓度相对滞后;污染物TN和CODMn输出总量远大于TP和氨氮,且污染物输出总量随雨强增大而增加,但并不呈线性增长关系;径流污染输出的TN和TP对金泾塘河水污染贡献较大。

Abstract: The output characteristics of pollutants in farmland runoff under different artificial rainfall intensity was researched at typical farmland in Changshu suburban area. The contribution of runoff pollution to the river pollution was also discussed. Result revealed that 1) the maximum concentration of pollutant appeared at the beginning of the rainfall under small intensity, while emerged later under big rainfall intensity; 2) the summation of TN and CODMn outputs were far larger than the output of TP and ammonia nitrogen, also the summation of pollutant increased with the increase of rainfall intensity but the change was nonlinear; 3) TN and TP had a greater contribution to the river contamination.

Key words: farmland, runoff, pollution, artificial rainfall, output characteristic
