摘要
户用沼气池建设不但改变了农村家庭能源消费结构,还带动了农村养殖业、种植业的发展。通过对江苏省涟水县农村家庭能源消费和沼气池使用等相关问题的人户调查,定量研究了户用沼气池建设所产生的影响。证明户用沼气池的使用能提高家庭能源利用效率,减少能源消费量和化肥的使用量,有利于农作物秸秆的还田,提高农户的生活质量。
The influence of using household biogas digesters on household energy consumption in rural areas based on the data from the survey of rural household energy consumption and household biogas digesters in Liangshui County was discussed . The results showed that rural household energy consumption depends mainly on the available local biomass energy and is primarily for such basic needs as cooking and breeding livestock. The development of biogas digesters leads to the obvious decrease of per capita energy consumption in rural families and biogas mainly takes the place of some stalk and straw and a few firewood but doesn' t substitute other forms of energy, especially conventional energy. Families with biogas digesters use most of the stalk and straw as organic fertilizer in fields. Rural families give common approvals to building biogas digesters. The survey proves that biogas digesters can effectively help improve the rural energy consumption structure, improve the quality of family life, cut down the total consumption of energy, increase the amount of straw and stalk used in fields, decrease the usage of fertilizer, and that most peasants in underdeveloped areas agree on developing biogas digesters.
