摘　　要：研究以三峡库区重庆段为研究对象,使用之前模拟试验得出的模型对该地区2010年非点源污染负荷产生量进行估算;结果显示2,010年三峡库区重庆段非点源污染负荷产生量为:COD 497 362 t、BOD254 853 t、氨氮34 431 t、总氮112 620 t、总磷31 274 t;在三类非点源污染中,农田地表径流占的比重最大,达到60%左右,农村生活污染次之,占到30%左右,城市地表径流占10%左右;最后,针对各类非点源污染,提出了相应的防治建议。Taking Chongqing section of Three Gorges Reservoir area as research object, this paper estimates the nonpoint resource pollution load amount in 2010 in this area by using the model obtained from previous simulation experiment,the results show that the nonpoint source pollution load amount of this area in 2010 is COD 497362t, BOD 254853 t, ammonia-nitrogen 3443 lt, total nitrogen 112620t, and total phosphorus 31274t, and that, in three classes of nonpoint source pollution, the ratio of surface runoff of the rural field is the biggest and reaches about 60% ,the ratio of rural living pollution is the second and amounts to 30% ,the ratio of urban surface runoff reaches 10%. Finally, according to all types of nonpoint source pollution, this paper proposes corresponding preventing suggestions.
