| 摘 要： | 联户沼气实施时间较短，对其经济及环境效益进行定量评价涉及甚少，为其大面积推广提供理论依据，笔者以河南省南阳市的联户沼气工程为例，从建设投资成本、运行维护成本、效益及净现值4个方面与单户沼气进行对比分析，并以卧龙区1个行政村的联户沼气工程的调查数据为样本，选取11个环境影响综合评价指标，运用层次分析法，借助SPSS13.0软件，对联户沼气工程进行环境效益综合评估。结果表明：联户沼气与单户沼气相比，建设成本户均减少支出507元；服务费用每年每户多分摊54.76元；净现值前者为54720.41元，后者为4332.11元，规模经济效益显著，其指数为115%，有更广阔的发展前景。2007-2009各年的环境效益综合分值分别为6.126、6.156、5.816，联户沼气工程对环境的影响介于“比较大”和“非常大”之间。
