摘  要:
农用地和畜禽养殖是农业领域氧化亚氮(N_2O)的重要排放源,估算省级农业活动N_2O的排放量,分析不同排放源的主要控制因素,对当地低碳农业发展意义重大。基于福建省农业活动水平数据,采用IPCC方法,以2005年为基准年,估算了2005年、2010年和2015年福建省农业活动N_2O排放量,结果表明:2005年、2010年和2015年福建省农业活动N_2O排放总量分别为3.41万、3.35万和3.29万t,2015年和2010年分别比2005年减少3.52%和1.76%;与2005年相比,2015年和2010年农用地的N_2O排放量分别减少1.67%和1.00%,畜禽养殖的N_2O排放量分别减少16.67%和7.14%。结合前人研究结果提出:农用地N_2O排放受作物品种、土壤条件、气候条件、田间管理措施以及人口因素等影响,其减排的关键是减少氮肥施用量;控制和减少畜禽养殖N_2O排放量的关键是优化畜牧业结构,提高规模化养殖水平,改良畜禽品种,改进动物饲养和畜禽排泄物处理技术,从源头上实现畜牧业的清洁生产。

摘  要:
Farmland and livestock operations are the major sources of environmental nitrous oxide(N_2O)emission generated from agricultural activities.Using the IPCC method,emission data were estimated and analyzed for 2005,2010 and 2015 aiming to mitigate the pollution in Fujian.The N_2O emissions from the agricultural activities in the province were 34 100 tin 2005,33 500 tin 2010,and 32 900 tin 2015.Compared to 2005,they were 3.52%in2015 and 1.76%in 2010 less,and the reductions on farmland emission were 1.67%in 2015 and 1.00%in 2010,while those on livestock emission,16.67%in 2015 and 7.14%in 2010.It appeared that the N_2O emission from farmlands was affected by the crops grown,soil conditions and fertilization practices on the land as well as the climate and resident population in the area,with nitrogen fertilizer application being the pivotal factor.For the livestock industry,optimizing husbandry structure,expanding operation scale,selecting appropriate breed,adopting advanced technology,and/or upgrading waste treatment program could benefit the pollution abatement effort.
