摘要: 粮食主产区在我国农业生产中具有举足轻重的地位,也是我国农业碳排放的主要来源.科学地把握当前我国粮食主产区农业碳排强度、区域差异及成因是合理构建农业碳减排政策体系、实现农业碳减排的重要前提.本文首先基于8 方面指标,运用主成分分析法对我国13 个粮食主产省(区)农业碳排强度进行测度,结果表明,湖南、山东、湖北农业碳排强度居前三位;吉林、黑龙江、内蒙古则位于后三位.在此基础上,构建农业碳排效应区域差异评价矩阵,对13 个地区进行聚类,结果显示,湖南、江西、河南、安徽4 省属于“高强度—低效益”地区;湖北、江苏、山东3 省属于“高强度—高效益”地区;四川、河北2 省属于“低强度—低效益”地区;黑龙江、吉林、辽宁、内蒙古4 省区属于“低强度—高效益”地区.最后,基于研究结论展开讨论.

Abstract: While the major grain producing areas in China play a vital role in agriculture, they have become the main source of agricultural carbon emission. Thus scientifically assessing current intensities of agricultural carbon emissions, discrepancies between the areas, and major causes in those areas is an essential prerequisite for making sound policies leading to reduction of agricultural carbon emission. To that end, based on 16 indexes, using principal components analysis, this paper presents the measurement of the agricultural carbon intensity in 13 major grain producing provinces. It shows that the carbon intensities of Hunan, Shandong and Hubei are among the highest three, while those of Jilin, Heilongjiang and Inner Mongolia are among the lowest three. An evaluation matrix of carbon intensity vs. benefits is then created to regroup the 13 areas. As shown in the results, Hunan, Jiangxi, Henan and Anhui are the high-intensity low-benefits areas; Hubei, Jiangsu and Shandong are thehigh- intensity high-benefits areas; Sichuan and Hebei are the low-intensity low-benefits areas; Heilongjiang, Jilin, Liaoning and Inner Mongolia are the low-intensity high-benefits areas.
