【摘要】：为使全国范围内畜禽污染防治工作的开展更具有针对性,基于对1992、2002、2012三年全国各省市畜禽养殖总量及各畜禽养殖量进行的热点分析比较,应用排污系数法对热点省份畜禽养殖排放的主要污染物进行了估算。结果表明,各类要素在各省市均不存在冷点,即不存在养殖量低值聚集区域,一定程度上可反映我国不存在养殖空白区。猪养殖的热点省份是四川、山东和湖南,牛养殖的热点省份是四川、山东和河南,羊养殖的热点省份是内蒙古和青海,均集中在我国西北部,家禽养殖的热点省份是山东和广东。养殖热点省份一般存在较严重的环境污染问题,畜禽养殖量聚集程度越显著,污染排放相对越多,对环境的威胁也越大。四川、河南、山东是畜禽养殖污染防控重点省份,养殖羊较多的内蒙古、新疆也是畜禽污染首要防控对象。
[Abstract]:In order to make the prevention and control work of livestock and poultry pollution more pertinence in the whole country, based on the analysis and comparison of the total amount of livestock and poultry breeding and the quantity of livestock and poultry breeding in various provinces and cities of China in the three years from 1992 to 2002 and 2012, The discharge coefficient method was used to estimate the main pollutants emitted from livestock and poultry breeding in hot provinces. The results show that there is no cold spot in all kinds of factors, that is, there is no low value accumulation area of culture quantity, which can reflect to some extent that there is no culture blank area in China. The hot spots for pig farming are Sichuan, Shandong and Hunan, the hot provinces for cattle farming are Sichuan, Shandong and Henan, and the hot provinces for sheep farming are Inner Mongolia and Qinghai, all concentrated in northwest China. The hot provinces of poultry farming are Shandong and Guangdong. There are serious environmental pollution problems in hot breeding provinces. The more the concentration of livestock and poultry is, the more pollution emissions are, and the greater the threat to the environment is. Sichuan, Henan and Shandong are the key provinces for pollution prevention and control of livestock and poultry. Inner Mongolia, where more sheep are raised, Xinjiang is also the primary object of pollution prevention and control of livestock and poultry.
