为探索上海地区农田径流污染物的生态拦截模式,在上海市环境科学研究院农业面源污染生态工程控制及生态恢复研究工作示范基地,开展了生态排水沟渠对农田径流营养性污染物的拦截净化效果的研究,并进行了工程尺度的应用示范。现场试验表明:生态沟渠对农田径流SS、TN、NH4+-N、TP均有一定的截留净化作用。工程示范结果显示:示范区内生态沟渠对SS、TN、NH4+-N、TP的净化效果总体上优于示范区外部普通农田排水沟渠。总体来看,生态排水沟渠对氮、磷等营养性污染物有较好的净化作用,可减轻周围环境受纳水体的污染负荷。
為探索上海地區農田徑流汙染物的生態攔截模式,在上海市環境科學研究院農業麵源汙染生態工程控製及生態恢複研究工作示範基地,開展瞭生態排水溝渠對農田徑流營養性汙染物的攔截淨化效果的研究,併進行瞭工程呎度的應用示範。現場試驗錶明:生態溝渠對農田徑流SS、TN、NH4+-N、TP均有一定的截留淨化作用。工程示範結果顯示:示範區內生態溝渠對SS、TN、NH4+-N、TP的淨化效果總體上優于示範區外部普通農田排水溝渠。總體來看,生態排水溝渠對氮、燐等營養性汙染物有較好的淨化作用,可減輕週圍環境受納水體的汙染負荷。

In order to explore the ecological retention modes for farmland runoff pollutants in Shanghai, in the demonstration base of ecological control and restoration for agricultural non-point pollution set up by Shanghai Academy of Environmental Sci-ences, the research on retention and purification effect by ecological drainage ditches on farmland runoff pollutants in Shanghai area and the engineering application demonstration were carried out. The field experiment studies shows that the ecological dit-ches have a certain effect of retention and purification on SS, TN, NH4+ -N and TP. The demonstration shows that effect of the ecological drainage ditch is superior to that of common ditches outside the demonstration zone. In general, the ecological drainage ditch has better purification effect on nitrogen, phosphorus and other nutrient pollutants, which can reduce the pollution load of surrounding environment for receiving farmland runoff water.
