摘　　要：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 one of new rural energy, which can reduce environmental pollution and solve the energy shortage in rural areas. The grey correlation analysis is used to analyze the driving force of rural household digesters development in five areas, which include population, economy, resources, energy consumption structure and the market. Based on the analysis of biogas surveys, this paper estimates that the main factors affecting rural household biogas development is the rural residents＇ net income, electricity, coal and the number of livestocks. The higher the income level, the more farmers will build digesters. But the higher income level can also lead to the lower biogas utilization efficiency. Future rural biogas in economically developed areas should be built more large-scale biogas projects, gradually reduced the rural household biogas and rural household biogas subsidies. In poor areas, it should be increased financial support more than before.
