基于温室气体排放的畜禽养殖大气环境承载力估算
Estimation of the atmospheric environment bearing capacity of livestock and poultry farming based on greenhouse gas emissions
摘要
Abstract
To address the challenge between greenhouse gas emissions reduction and animal husbandry development,this study developed a method to estimate the atmospheric bearing capacity of livestock and poultry farming based on greenhouse gas emissions.The intensity of greenhouse gas emissions was calculated,and by combining it with the threshold values,the regional animal breeding potential was assessed through simulation.The results showed that:1)From 2010 to 2021,the greenhouse gas emissions intensity in livestock and poultry farming in Xinjiang Production and Construction Corps(XPCC)displayed a"first rising and then falling"trend;By 2021,the intensity of emissions reached 1 544.50 kg/hm2,with N2O emissions from farmland soil and CH4 emissions from animal intestines being the main emissions sources.Similarly,Beidahuang Group(BG)exhibited a"first rising and then failing"trend.The intensity emissions was 3 125.40 kg/hm2 on 2021,which was largely due to CH4 emissions from rice fields and N2O emissions from farmland soil.2)The livestock and poultry farming in both XPCC and BG remained within the atmospheric bearing.The future potential estimated,measured in pig equivalents,is 4.234 million to 21.17 million for XPCC and 7.335 million to 36.675 million for BG,respectively.It was recommended that the two regions should focus on promoting emissions reduction technologies for rice fields,efficient water and fertilizer management,and advancing high-quality mechanization in agriculture and animal husbandry,as well as enhancing soil carbon sequestration.This study provided valuable insights into the integration of crop and livestock production with atmospheric environmental protection in the future.关键词
