Estimation on Nonpoint Source Pollution Load Amount in Chongqing Section of Three Gorges Reservoir Area
摘要
Abstract
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.关键词
