摘要
文中在分析我国地区农业碳排放现状的基础上,从农业碳排放总量、人均碳排放和碳排放强度等方面对我国农业碳排放的区域差异进行了评价,最后运用LMDI因素分解模型对影响各地区农业碳排放的主要因素进行了实证分析。结果表明:从农业碳排放总量来看,各地区呈现持续增长的趋势,西部增长最快,东部地区农业碳排放呈现波动阶段性特征,特别是近几年增长速度下降。农业碳排放总量和碳排放强度的区域差距表现出逐渐缩小的趋势。农业经济发展水平是影响各地区农业碳排放增长的主要因素,农业能源利用效率的提高、内部结构的优化和农业劳动力的转移都有助于农业碳减排。相比于东西地区,效率因素更有助于中部的碳减排。相比于中西部,农业内部产业结构的优化和农业劳动力转移更有助于东部的碳减排。
Based on carbon emissions for agriculture in China,we assessed the area differentiation of carbon emissions in agriculture,examined the influential factors of carbon emissions for agriculture in China. The results show that the whole country＇s agricultural carbon emissions performance was increasing. The agricultural carbon emissions in west region increased rapidly. The area differentiation of agricultural carbon emissions in China decreased. In general,the major driver of carbon emissions was agricultural development level. Industrial structure,energy efficiency and labor transfer had significant effects on agricultural carbon emissions performance.
