摘要: 农业是重要的温室气体排放源之一,准确分析农业温室气体的排放特征可为制定和更新低碳化政策及措施提供重要依据。根据浙江省嘉兴市相关统计资料,参照《浙江省温室气体清单编制指南(2017年版)》温室气体核算方法,分析了嘉兴市2010—2016年农业温室气体的排放特征。结果显示:嘉兴市农业温室气体减排工作成效显著,年均减排幅度达8.4%,2014年较2013年减排20.2%;种植业是嘉兴市农业温室气体的主要来源,排放占比最大的温室气体排放源依次为化肥氮、稻田甲烷和与羊养殖相关的排放源,2016年,三者分别占嘉兴市农业温室气体排放总量的40.2%、36.0%和10.5%;种植业发展规模较大的桐乡市和平湖市农业温室气体排放量位居嘉兴市前2位;种植业和畜牧业体量都不大的嘉善县,农业温室气体排放量总体相应较小。稻田甲烷减排、合理施用化肥将是未来嘉兴市低碳农业发展的重点。

Abstract: Agriculture is the major source of greenhouse gas emissions. The systematic analysis of agricultural greenhouse gas emission characteristics could provide basis for making and updating reasonable low carbon development policies. Based on the collected agricultural data of Jiaxing City, according to the methodology recommended by 2017 Guidelines for Greenhouse Gas Inventories of Zhejiang Province, the characteristics of agricultural greenhouse gas emissions of Jiaxing City were analyzed. The results showed as follows: Notable reduction of agricultural greenhouse gas emission in Jiaxing city had been achieved from 2010 to 2016, there was a significant reduction (20.2%) in 2014 compared with 2013. The averaged annual reduction rate of agricultural greenhouse gas emission reached 8.4%. Crop farming was the most important agricultural greenhouse gas emission source in Jiaxing City. Application of inorganic fertilizer-nitrogen, rice plantation and sheep husbandry had become the top three emission sources, accounting for 40.2%, 36.0% and 10.5% of the total in 2016, respectively. Tongxiang and Pinghu Cities with developed crop farming were ranked the top two agricultural greenhouse gas emissions in whole Jiaxing region, while that of Jiashan City was low because of its balanced agricultural development. In summary, development of low carbon agriculture in Jiaxing City should focus on reducing paddy CH4 emission and rational use of chemical nitrogen fertilizers in future.
