农村户用沼气发酵原料产气潜力及区划研究

结合能值潜力估算动物数据库模型,建立了中国农村户用沼气主要发酵原料理论户均产气潜力估算模型。并利用该模型对2007年中国农村主要沼气发酵原料理论户均产气潜力进行了估算。结果表明:发酵原料理论户均产气潜力居前五位的是西藏、青海、吉林、内蒙古和新疆,均高于2 300m3/a,其中西藏高达9 492m3/a,山西、上海、福建、广东、重庆、陕西和浙江发酵原料理论户均产气潜力较低,均低于540m3/a。在此基础上,构建了农村户用沼气发酵原料区划指标,对中国各地农村沼气发酵原料理论户均产沼气潜力进行分区,划分为沼气发酵原料最适宜区、适宜区、次适宜区和非适宜区。根据区划结果,形成了中国农村户用沼气发酵原料适宜性区划图。

Research on Production Potential and Regionalization of Household Biogas Fermentation Materials in Rural Area of China

Theoretical biogas production potential estimation model of fermentation materials was established based on animal data base for energy potential estimation(ABEPE) model.The model was used to estimate Chinese rural household biogas production in 2007.The results showed that the top five areas were Tibet,Qinghai,Jilin,Inner Mongolia and Xinjiang in China in terms of the theoretical biogas fermentation material production potential higher than 2 300 m3/a,the theoretical biogas fermentation material production potential in Tibet was up to 9 492 m3/a;the theoretical biogas fermentation material production potentials in Shanxi,Shanghai,Fujian,Guangdong,Chongqing,Shaanxi and Zhejiang were lower than 540 m3/a.According to the fermentation material suitability,the development of household biogas could be divided into four different regions in rural area of China which include optimum region,suitable region,sub-suitable region and unsuitable region.According to these results,biogas fermentation material zoning map in rural area of China was made.
