湖北省大冶市畜禽养殖土地承载能力分析

Approach on Livestock Carrying Capacity of Farmland at Daye City in Hubei Province

摘要: 通过农作物种植面积计算农田畜禽承载量,并利用各类畜禽产排污系数估算区域畜禽理论养殖量,分析大冶市农田畜禽承载量与畜禽实际养殖量的耦合关系。研究表明:大冶市畜禽理论承载能力为120万头猪当量，合理承载力为60万头猪当量；2016年大冶市畜禽存栏量折合生猪106万头，已经超出了环境承载能力。对此提出了调控对策。

Abstract: Actual livestock and poultry breeding capacity was calculated by using area under crops and amount of breeding livestock based on modulation, crops planting area and polluting coefficient to calculate the volume. The research result revealed that the theoretical acreage of crops was 1.20 million in counting of pigs. However, the reasonable capacity was no more than 0.6 million in counting of pigs. Meanwhile the livestock and poultry currently are 1.06 million in counting in pig at Daye City in 2016. It suggested that the carrying capacity of livestock of farmland in Daye has already overloaded. Thereby some policies were proposed for improving the administration.
