研究采煤地区农户生活用能的碳排放,有助于更好地认识和制定农村减排的相关政策。以渭北“黑腰带”中部白水县地下采煤区为例,采用对比分析法、联合国政府间气候变化专门委员会(IPCC)的碳排放计算方法,定量探究采煤地区农户生活用能的碳排放及其影响机制。结果表明,采煤地区农户生活用能的碳排放(1 639.56 kg C/户)少于非采煤区(1 747.77 kg C/户),前者主要来源于煤炭、薪柴、电能,三类能源贡献了96%以上,煤炭达61.72%;后者主要为薪柴、煤炭、秸秆、电能,较分散多元,整体以薪柴(41.30%)为主。采煤地区农户商品性能源消费1 443.2 kgce/户,非采煤区为1 014.47 kgce/户,没有呈现用能结构向商品化转变而碳排放增多的状况。碳排放与用能类型、使用数量及排放系数相关,有碳排放的能源使用数量越多,排放系数越大,碳排放量越多。采煤是造成农户生活用能及其碳排放较正常状况下有所差异的根源和主要诱因。应改良用能灶具以提高利用热效,增加沼气等新型用能份额,关注用能的区域差异带来的不同排放效果。
Studying carbon emissions from domestic energy use in coal mining areas will help to better understand and formulate policies on rural emission reduction. Taking the underground coal mining area of Baishui County in Weibei “Black Belt ” as an example, comparative analysis method and carbon emission calculation method of the United Nations Intergovernmental Panel on Climate Change (IPCC) were used to quantitatively study the energy consumption of farmers in coal mining areas Carbon Emissions and Its Impact Mechanism. The results show that the carbon emission (1,639.56 kg C / household) for household energy use in coal mining area is less than that in non-coal mining area (1 747.77 kg C / household). The former is mainly derived from coal, fuelwood, electricity, Contributing more than 96% of coal and 61.72% of coal. The latter is mainly fuelwood, coal, straw, electric energy, and more diversified and diversified, with the overall proportion of fuelwood (41.30%). The energy consumption of peasant households in the coal mining areas was 1 443.2 kgce / household and that of non-coal mining areas was 1 014.47 kgce / household, showing no increase in carbon emissions due to commercialization of energy-using structures. Carbon emissions are related to the type of energy used, the amount used and the emission factor. The more carbon is used, the more the emission factor is and the more the carbon is emitted. Coal mining is the root cause and main inducing factor of household living energy consumption and carbon emissions under normal conditions. Improve the use of energy-saving stoves to improve the use of thermal efficiency, increase the share of new energy such as biogas, pay attention to the use of different regional differences bring about different emissions.
