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.
