摘要
分析了吉林省农业生产温室气体排放系数,对2000-2014年吉林省温室气体排放量进行了估算.结果表明:①2000-2014年吉林省温室气体排放量由l 927.94万t增长到2445.25万t,经历了快速上升、快速下降和缓慢上升3个阶段,目前吉林省正处于农业温室气体排放上升阶段,减排压力较大;②2000-2014年吉林省温室气体中CH4的排放贡献率为41.41％,N2O的排放贡献率为58.69％;③2000-2014年农用地N,O是吉林省温室气体第一排放源,年均所占比重为46.32％,其他温室气体排放量从大到小依次为动物肠道CH4、动物粪便管理N2O和稻田CH4,所占比重分别为29.83％、14.11％、10.41％.最后,依据吉林省温室气体排放量和结构特征,从农业生产角度提出了减排措施.
Abstract
The agricultural production activity coefficient of greenhouse gas,and estimated the agricultural production greenhouse gas emissions in Jilin Province from 2000 to 2014 were analyzed.Results showed that:① Agricultural greenhouse gas emissions increased from 19.279 4 million tons to 24.452 5 million tons in Jilin Province from 2000 to 2014.It experienced three stages of rapid rise stage,rapid decline stage and slow rise stage from 2000 to 2014.At present,the pressure to reduce emissions is increasing with the increase of agricultural greenhouse gas emissions in Jilin Province.②The CH4 emissions of greenhouse gases accounted for 41.41％,the N2O emissions of greenhouse gas accounted for 58.69％ in Jilin Province from 2000 to 2014.③N2O emission of agricultural land was the first source of emissions in Jilin greenhouse gas emissions,accounted for annual average of 46.32％ from 2000 to 2014..Other greenhouse gas emissions in turn were animal intestinal fermentation CH4 emission,animal waste management N2O emission and paddy field CH4 emission,accounted for 29.83％,14.11％ and 10.41％,respectively.Finally,the mitigation measures were put forward from the aspect of agricultural production according to emissions and structure characters of greenhouse gas in Jilin Province
