沼气是农村新能源的主体,可以减少环境污染、解决农村能源短缺问题.从人口、经济、资源、能源消费结构和市场五个方面,用灰关联方法分析了农村户用沼气发展的推动力,并通过实地调研验证了研究结论.结果表明,影响农村户用沼气的发展的主要因素是农村居民人均年纯收入、电力、煤和大牲口存栏数;收入水平越高,农户越能接受沼气池建设,但也会导致沼气池使用效率下降.建议经济发达地区逐渐取消农村户用沼气,建设大型沼气工程,同时加大贫困地区资金扶持力度,削减经济发达地区户用沼气建设补贴.
Biogas is the main body of new energy in rural areas, which can reduce environmental pollution and solve the problem of rural energy shortage.According to five aspects of population, economy, resources, energy consumption structure and market, the driving force of household biogas development in rural areas is analyzed by gray correlation method, And verified the conclusions through field research.The results show that the main factors affecting the development of household biogas in rural areas are per capita annual net income of rural residents, electricity, coal and large livestock population; the higher the income level, the more farmers can accept the digester It is also suggested that the economically developed areas gradually cancel household biogas in rural areas and build large-scale biogas projects, at the same time, it will increase financial support for poor areas and reduce subsidies for household biogas construction in economically developed areas.
