摘要
本文基于甘肃省农业碳排放持续增长的发展现状,采用碳排放系数法测算分析2010—2021年时空尺度下甘肃省农业碳排放总量、强度和结构,并以甘肃省14个市(州)为样本,比较各地农业碳排放区域差异,运用Tapio脱钩模型分析其与农业经济发展间的脱钩关系。研究表明,2010年以来,甘肃省农业碳排放总量呈“快速上升—快速下降—快速上升”三阶段“N”形变化趋势;甘肃省各市(州)农业碳排放总量大部分经历了先升后降的演化进程,空间上呈现出“中部高、东西两端低”的分布格局,部分市(州)在畜牧业高速发展期间农业碳排放总量大幅度上升;甘肃省农业碳排放与农业经济总体经历了“弱脱钩—强脱钩—弱脱钩”的变化历程,考察期内脱钩态势良好。
Based on the development status of continuous growth of agricultural carbon emissions in Gansu,this paper uses the carbon emission coefficient method to estimate and analyze the total amount,intensity and structure of agricultural carbon emissions in Gansu from 2010 to 2021 on a spatial-temporal scale,and compares the regional differences of agricultural carbon emissions among 14 cities and prefectures in Gansu.Then,the Tapio decoupling model is used to analyze the decoupling relationship between agricultural carbon emissions and agricultural economic development.The results show that since 2010,the total agricultural carbon emissions in Gansu showed a three-stage change trend of"rapid rise-rapid decline-rapid rise",which was vividly represented as"N"shape.Most of the total carbon emissions of the cities and prefectures in Gansu experienced a long-term evolution process of first rising and then falling,showing a spatial distribution pattern of"high in the middle and low at both ends".During the rapid development of animal husbandry,the total agricultural carbon emissions of some cities and prefectures increased significantly.Agricultural carbon emissions and agricultural economy in Gansu experienced a change process of"weak decoupling-strong decoupling-weak decoupling",and the decoupling trend was good during the investigation period.
