摘　　要：该文以湖北恩施州农村户用沼气池项目为例,利用《联合国气候变化框架公约》清洁发展机制理事会批准的方法学AMS-Ⅲ.R和AMS-I.C,分析了农村户用沼气池建设减少温室气体排放的潜力。项目位于湖北省西南部的贫困地区,涉及8个县市的33000个农户。研究表明:户用沼气池的建设既能减少目前粪便管理方式造成的CH4排放,又能充分利用可再生能源,减少化石燃料的使用和减少CO2温室气体排放,预计每个农户可实现温室气体减排1.43～2.0t二氧化碳当量,整个项目实现年减排温室气体58444t二氧化碳当量。Taking Hubei Enshi household biogas project as a case study, greenhouse gas emission reduction potential of installing household biogas digesters was analyzed by using methodologies （AMS-Ⅲ.R and AMS-Ⅰ.C） approved by Executive Board （EB） of clean development mechanism （CDM） under United Nation Framework Convention on Climate Change. The project involved in 33 000 households in 8 counties of Enshi Prefecture, a mountainous poor area of Hubei Province, China. The analysis showed that installing biogas digesters could reduce CH4 emission from the manure management by fermenting manure in the biogas digester instead of being stored in a deep pit, and utilize the renewable energy of biogas. It is expected that the installation of biogas digester could reduce GHG emission of 1.43-2.0 t CO2 equivalent for each household. The estimated annual emission reduction for the project will be 58 444 t CO2 equivalent.
