中国农村生活用能及其碳排放分析(2001-2010)

分析了2001~2008年中国农村生活用能的变化以及2001~2010年中国农村生活用能对气候变化的影响。研究发现,农村生活用能呈现了从非商品能源向商品能源转变的趋势,其中,传统生物质能源的消费比例从81.5%下降至70.9%,而商品能源则从17.1%上升至25.1%。此外,除传统生物质能源外的其它可再生能源的消费增长迅速,年均增长率为19.8%。与此相应,农村生活用能消费所导致的碳排放呈现出显著的增加趋势,由152.2百万t上升至366.89百万t,且农村人均CO2排放的增长速度是同期城镇人口的1.87倍。分析认为,影响商品能源消费的主要因素是农村居民收入的增加,强有力的政策支持则促进了农村除传统生物质能源外其他可再生能源的发展。

Analysis of rural residential energy consumption and its carbon emission in China,2001-2010

The analysis of rural residential energy consumption in China from 2001 to 2008 and its impacts on climate change from 2001 to 2010 was presented in this paper.Results showed that rural residential energy consumption has shown obvious transition from non-commercial energy to commercial energy.The percentage of traditional biomass energy consumption has dropped from 81.5% in 2001 to 70.9% in 2008,while the percentage of commercial energy has increased from 17.1% to 25.1%.Besides,renewable energy except traditional biomass has increased very fast during the years of study with annual growth rate of 19.8%.Correspondingly,total CO2 emission from rural residential energy consumption has significant increased from 152.2 Million tons in 2001 to 367.89 Million tons in 2010.The annual growth rate of per capita CO2 emission is 1.87 times faster than that of urban areas.It is argued the major driving force for the consumption of the commercial energy is the income of rural farmers,while strong rural energy policies support the development of other renewable energies except traditional biomass.
