摘　　要：利用LMDI因素分解模型无残差优势对甘肃省2005~2020年农业碳排放量进行测算,根据测算结果对甘肃省农业碳排放变化趋势及影响因素进行分析。结果表明:2005~2020年,甘肃省的碳排放总量呈现波动式上升趋势,碳排放强度呈现逐年下降趋势;碳排放量增加主要来源于化肥的使用和土地翻耕引起的碳排放量;农业经济和产业结构是驱动碳排放的主要因素,对甘肃省碳排放有促进作用。在此基础上,针对农业碳排放影响因素,提出甘肃省低碳农业发展的实现路径,为进一步实现“双碳”目标提供依据。In this paper,the non-residual advantage of the LMDI factor decomposition model is used to calculate the agricultural carbon emissions in Gansu Province during 2005~2020.According to the calculated results,the changeable trend and influencing factors of the agricultural carbon emissions in Gansu Province are analyzed.The results demonstrate that the total carbon emission in Gansu Province displays a fluctuating upward trend,while the carbon emission intensity proves a downward trend year by year from 2005 to 2020;the increase of carbon emissions mainly comes from this carbon emissions caused by the use of the chemical fertilizers and the tillage of land;the agricultural economy and industrial structure are the main driving factors of carbon emission,which promoting the carbon emission in Gansu Province.According to the influencing factors of the agricultural carbon emissions,we put forward the realizable path of developing low-carbon agriculture in Gansu Province,aiming to provide a basis for further achieving the goal of"double carbon."
