摘要
本文采用实地调研与线上调研相结合的方式,选取宁夏典型村镇,研究用能现状及特性,并结合当地可再生能源特征,提出了因地制宜的用能指导措施。宁夏村镇供暖方式以燃煤炉、火炕为主,使用率达到了79.03%和74.19%,采暖能耗(标准煤)集中在2000~4000 kg,偏相关分析表明采暖能耗与供暖方式和建筑面积显著相关。生活热水来源以煤灶、柴火灶为主,使用率达到了93.89%和82.22%,炊事以电饭煲、电磁炉、柴灶为主,使用率分别为75.56%、71.11%和64.44%。宁夏村镇可再生能源利用率较低,为9.53%,在利用的可再生能源中,太阳能的比例最高,光热占85.45%,光伏占42.22%。本研究可为宁夏村镇的节能降碳工作提供基础数据支撑,为构建绿色低碳、清洁高效的村镇能源体系提供参考对策。
This paper selected typical villages in Ningxia,adopted the method of field investigation and online investigation to study the current situation and characteristics of energy consumption,and proposed energy consumption guiding measures according to the characteristics of local renewable energy.In Ningxia villages,coal⁃fired furnaces and kangs are the main heating methods,with utilization rates reaching 79.03%and 74.19%.The heating energy consumption is concentrated in 2,000-4,000 kgce.Partial correlation analysis shows that the heating energy consumption is significantly correlated with heating methods and building area.The main sources of domestic hot water are coal stoves and wood stoves,with utilization rates reaching 93.89%and 82.22%.The main sources of cooking water are electric cookers,induction cookers,and wood stoves,with utilization rates reaching 75.56%,71.11%,and 64.44%,respectively.The utilization rate of renewable energy is low,only 9.53%.Among the renewable energy used,solar energy accounts for the highest proportion,with solar heat accounting for 85.45%and photovoltaic for 42.22%.This study can provide basic data support for energy saving and carbon reduction in the field of rural buildings in Ningxia,and provide reference countermeasures for the construction of a green,low⁃carbon,clean,and efficient rural energy system.
