| 摘要: |
| 目的 农业生产活动产生的碳排放已经成为我国碳排放主要组成部分，因此研究农业生产活动过程中产生的碳排放对推动农业低碳减排具有重要作用。方法 文章基于2012—2021年西部地区12省、市、自治区的数据，从作物种植、牲畜养殖和农业物资投入3类碳源对西部地区农业碳排放总量进行测算，再运用社会网络分析法对测算出的西部地区农业碳排放进行空间关联网络特征结果分析。结果 （1）西部地区农业碳排放总量呈现上升－下降－上升趋势；（2）西部地区农业碳排放空间关联网络整体特征相对稳定并且各地区间的空间相互作用不断增强；（3）西部地区农业碳排放空间关联网络的中心由四川、西藏、青海和宁夏变为四川、西藏、青海和新疆。结论 西部地区农业碳排放影响要素间的关联作用不断增强，提高农地利用效率、优化农业产业结构和改善农业生态环境可以有效降低农业碳排放，从而为西部地区进行碳减排策略制定提供参考。 |

| Abstract: |
| Carbon emissions from agricultural production activities become a major component of China's carbon emissions. To help in the understanding of agricultural emissions in China, this study explores the carbon emissions from agricultural production activities. Based on the data of 12 provinces, municipalities and autonomous regions in the western China from 2012 to 2021, the total agricultural carbon emissions were measured from three types of carbon sources: crop planting, livestock breeding and agricultural material input. The spatial correlation network characteristics of the calculated agricultural carbon emissions in the western China were analyzed by using social network analysis. The results were indicated as follow. (1) The total agricultural carbon emissions in western China showed an upward-downward-upward trend; (2) The overall characteristics of the spatial correlation network of agricultural carbon emissions in western China were relatively stable and the spatial interaction among provinces was continuously enhanced; (3) The absolute center of spatial correlation network of agricultural carbon emissions in western China is SiChuan Province.The correlation between influencing factors of agricultural carbon emission in western China has been continuously enhanced, which provides references for carbon emission reduction strategies in western China from three aspects: improving agricultural land utilization efficiency, optimizing agricultural industrial structure and improving agricultural ecological environment. |
