为了给养殖场择优选取适宜的粪污资源化利用模式提供参考，研究基于湖南省生猪规模养殖场的实地调研数据，以四种养殖粪污资源化利用典型模式（种养结合-全量还田模式、种养结合-能源化模式、清洁回用模式、达标排放模式）为研究对象，从经济、生态、社会三方面构建指标体系，运用TOPSIS综合评价法对不同规模养殖场的四种粪污资源化利用模式进行了综合效益评价。结果表明：小规模养殖场综合效益由高到低依次为清洁回用模式、种养结合-全量还田模式、种养结合-能源化模式、达标排放模式；中规模养殖场综合效益由高到低依次为种养结合-全量还田模式、清洁回用模式、种养结合-能源化模式、达标排放...

In order to provide reference for the preferential selection of the manure and sewage resource ultilization model, this study took four typical modes of fecal and sewage resource utilization in breeding as the research objects(the mode of combining planting and raising with full amount return to the field, the mode of combining planting and raising with energy, the mode of clean reuse and the mode of standard discharge) based on the field survey data of large-scale pig farms in Hunan Province. An index system was constructed from three aspects of economy, ecology and society, and the comprehen...
