目前中国面临着严峻的农业非点源污染形势,而畜禽养殖是其中的一个重要方面。以濑溪河流域(泸县境内)10个城镇为例,对畜禽养殖所引起的农业非点源污染进行了研究。结果表明:濑溪河流域(泸县境内)集中式畜禽养殖对水体污染小;散养型畜禽养殖对水体污染严重,主要污染物为COD和NH_3~-N,其中福集镇的畜禽养殖污染贡献度最大,对此提出了合理的建议及措施来减轻研究区的畜禽养殖污染。
At present, China is facing a serious agricultural non-point source pollution situation, and livestock and poultry farming is one of the important aspects. Taking the 10 towns of Seto River Basin (within Luzhou County) as an example, the agricultural non-point source pollution caused by livestock and poultry breeding was studied. The results showed that centralized livestock and poultry breeding in Seto River Basin (within Luxian County) had less pollution to water body; and that of free-range livestock and poultry breeding was seriously polluted by water body. The main pollutants were COD and NH_3 ~ -N, The contribution of aquaculture pollution is the largest, and reasonable suggestions and measures are put forward to alleviate the pollution of livestock and poultry breeding in the study area.
