摘要
能源消费会产生大量的温室气体,主要为CO2、CH4或N2O等,通过温室气体排放量估算中国1990—2008年农村生活用能足迹显示:近20年来中国农村生活用能总足迹增长趋势明显,年均增长7.32%;薪柴、秸秆和煤炭足迹比重持续降低,沼气和电力足迹比重显著上升。利用恩格尔系数作为中国农村富裕程度的衡量指标,考察农村富裕程度对各类生活用能足迹的影响,结果表明:恩格尔系数对薪柴、秸秆足迹的影响作用不甚明显,与煤炭足迹同向变动,与沼气、电力足迹和总足迹反向变动,影响作用显著。
This paper estimates China's rural household energy's footprint from 1990 to 2008. The results showed that: 1) in the last 20 years, the increasing trend of rural household energy's footprint was very significant, 7.32% annually; 2) the footprint of firewood, straw and coal continued reducing while the footprint of gas and power increasing significantly; 3) Engel's coefficient influenced the firewood and straw so little, and changed in the same direction with coal footprint; However, Engel's coefficient changed reversely with the gas, power footprint; 4) compared with other energy, power footprint was sensitive to change of rural affluence. The paper provided a reference for the China's rural energy development.
