农村可再生能源建设对农户的社会经济影响:以沼气生态系统为例

Social-economic Impacts of Rural Renewable Energy on Farmer Households:Based on Example of Biogas System

农村沼气是农业生物质能的一个重要组成部分。本文分析了四个省沼气生态系统发展对于农户所产生的社会经济影响,具体包括以下影响:收入水平、收入来源、缓解贫困、农产品生产和销售、能源消耗、化肥农药投入、节省的劳动力和时间、卫生和健康。本研究还比较了不同的沼气生态系统模式的优势和不足,以及对不同类型农户的适宜性。最后,本文就沼气生态系统在农村的发展提供了建议和对策。
