| 摘 要： | 理清影响农业低碳发展的关键因素有助于农业现代化的顺利实现.本研究对Kaya恒等式进行扩展,将农业碳排放分解为一般技术、农业低碳技术、农村生活水平、间接城镇化与总人口变动等因素,通过差额分析因素分解方法分析以上因素对中国农业碳排放的驱动方向与贡献率,发现农村生活水、城镇化以及总人口变动因素正向影响农业碳排放变动,而一般技术与农业低碳技术因素则负向影响农业碳排放变动.从各因素变动引起农业碳排放的无方向贡献看有下列关系:农村生活水平效应农业低碳技术效应间接城镇化效应一般技术效应总人口变动效应.

| Abstract: | Agricultural modernization is a transition process from traditional agriculture to modarn agriculture, and the low-carbon agricultural way is an important approach in this transition. This study decomposes the CO2 emission into five contributory factors based on an expanded Kaya identity. The five factors are general technology, agricultural low-carbon technology, rural affluence, indirect urbanization, and total population scale. With the incremental analysis we find that the rural affluence, urbanization, and total population scale are driving the agricultural CO2 emission positively, while the general technology and agricultural low-carbon technology are driving the agricultural CO2 emission negatively. Contribution without direction to total agricultural CO2 emission caused by alteration of each factor is exhibited as: rural affluence influence > agricultural low-carbon technology influence > indrect urbanization influence > general technology influence > total population scale influence. |
