摘要
通过农田降雨径流监测试验,并对上海市历时23年的逐日降雨资料进行汇总与系统分析,确定黄浦江流域农田地表降雨径流特征。结果表明:全年黄浦江流域农田地表降雨径流系数在O.35～0.52,地表能够产流的降雨日约为18天,农田耕地产生的地表径流量为2700m^3/hm^2,其中85％集中在汛期5～9月份。
Through monitoring farmland runoff and analyzing daily rainfall for 23 years in Shanghai, this paper provided the characteristics of farmland rainfall runoff in Huangpu River Basin. The results showed that the farmland runoff coefficient in Huangpu River Basin was 0.35 - 0.52, there were 18 rain days with farmland runoff in one year, and 2700mVhm2 of farmland runoff, among which 85% was concentrated in the flood season (May to September).
