农村户用沼气区域适宜性研究

Research on Regional Suitability of Rural Household Biogas

对我国农村户用沼气适宜性区域划分研究现状进行总结,指出农村户用沼气适宜性评价研究的不足。通过分析确定农村地区户用沼气区域适宜性的评价指标,包括户均畜禽排泄物产气量、农民人均纯收入以及气温。确立评价方法及评价标准,将农村地区划分为户用沼气发展的适宜地区、次适宜地区、不适宜地区以及转变发展模式地区。在此基础上,对农村地区户用沼气适宜性进行区域划分。结果表明,安徽、江西、河南、湖北、湖南、广西、海南、重庆、四川、贵州、云南为户用沼气发展的适宜地区,河北、山西、内蒙古、辽宁、吉林、黑龙江、山东、西藏、陕西、甘肃、青海、宁夏、新疆为户用沼气发展的次适宜地区,北京、天津、江苏、浙江、广东、福建为户用沼气发展的转变发展模式地区。

The research status of regional division of rural household biogas suitability in China is summarized, and the insufficiency of rural household biogas suitability evaluation research is pointed out. The evaluation methods and evaluation criteria are established through the analysis to determine the evaluation index of the regional suitability -of household biogas in rural areas, including the amount of biogas produced by livestock and poultry excreta per household, the per capita net income of farmers and the air temperature. The rural areas are divided into suitable areas, subsuitable areas, unsuitable areas and transforming development pattern areas for household biogas development. On this basis, the regional division of household biogas suitability in rural areas is performed. The results show that Anhui, Jiangxi, Henan, Hubei, Hunan, Guangxi, Hainan, Chongqing, Sichuan, Guizhou, and Yunnan are suitable areas for household biogas development. Hebei, Shanxi, Inner Mongolia, Liaoning, Jilin, Heilongjiang, Shandong, Tibet, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang are sub-suitable areas for household biogas development. Beijing, Tianjin, Jiangsu, Zhejiang, Guangdong and Fujian are transforming development pattern areas for household biogas development.
