巢湖流域农村畜牧业发展与非点源污染研究

Study on Stockbreeding of Chaohu Lake Basin and Non—point Source Pollution

目前,巢湖流域非点源污染问题突出。着眼于畜牧业和环境的协调发展,通过对研究区畜牧业生产的实地考查、分析和计算得出结论:畜牧业生产的快速发展、不合理和未加利用的畜牧粪便及畜牧业产品生产加工过程中产生的有机污物是巢湖流域非点源污染的重要原因,来源于畜牧业生产的非点源污染的氮就足以使巢湖水质劣于Ⅲ类标准。最后探讨了解决巢湖富营养化的控制措施。

At present, it was confronted in the area of Chaohu Basin with the problem of now-point source pollution. For the purpose of the harmony of environment and stoekbreeding, according to studying stoekbreeding of this area and ealculation,such conclusion was made that another important cause was the fast development of stock raising,unused or unreasonably used livestock dejection and the organic contamination produced in the procession of livestock product. The azote in the non - point source pollution debased the water quality to worse than Ⅲ, Some approaches on stock raising designed for controlling non- point source pollution of Chaohu Basin were suggested in the end.
