广东省种植业能源消费温室气体排放影响因素研究

利用能量分析法研究了1993-2013年广东省种植业能源消费温室气体排放的变化特征和结构特征。运用LMDI分解方法分析了1993-2013年广东省种植业能源消费温室气体排放变化的主要影响因素。结果表明,1993-2013年广东省种植业能源消费温室气体排放具有较为明显的增长。化肥的使用是广东省种植业温室气体的主要排放源。农业经济水平和能源强度分别是主要增排因素和减排因素。能源强度因素对广东省种植业能源消费温室气体排放的减排作用不稳定且具有较大提升空间。

Factor Analysis of the Energy Consumption Related Greenhouse Gas Emissions From Crop Production System in Guangdong Province

Energetic analysis method was used to analyze the change characteristics and structure characteristics of energy consumption related greenhouse gas emissions from crop production system in Guangdong Province during 1993-2013. Utilizing Logarithmic Mean Divisia Index (LMDI) method, this paper studied the main factors that affected the energy consumption related greenhouse gas emissions. The results of the study show that the energy consumption related greenhouse gas emissions have increased greatly in Guangdong"s crop production system from 1993 to 2013. It also indicates that chemical fertilizers are the main sources of energy and greenhouse gas emissions. Among all main factors, the level of agricultural economy is the determining factor for the growth of greenhouse gas emissions, while energy intensity is the main factor to reduce these emissions. The reduction effect of energy intensity on energy consumption related greenhouse gas emissions of crop production system in Guangdong Province was not stable and has a large room to improve.
