中文摘要:
      户用沼气的区域适宜性评价是户用沼气合理布局的关键。针对我国农村户用沼气的发展现状，系统分析了影响我国农村户用沼气发展的区域因素，依据评价指标建立的原则从气候条件、能源状况、社会经济因素3个方面选择了年平均温度、≥10℃持续天数、生物质资源量、商品能源获取的难易程度、户年均收入、国家投资和农民平均文化水平7个评价指标，构建了农村户用沼气区域适宜性评价指标体系；运用层次分析法确定了农村户用沼气区域适宜性分级标准，其中适宜性总分值大于等于80的区域，为最适宜区，适宜性总分值在80～60的区域，为适宜区，总分值在60～40的区域，为次适宜区，总分值小于40的区域，为不适宜区。
英文摘要:
      The household biogas region suitability evaluation is the key to the reasonable layout of the household biogas. Based on the current situation of rural household biogas growth in China, analysis was made of the regional factors influencing the development of the household biogas. Seven evaluation indexes (mean annual temperature、days with temperature above 10℃, quantity for biomass, difficulty of the commodity energy obtained, revenue per family, government investment, average education level of farmer) from 3 catalogues-climate, energy stuation and social economy factors were chosen to set up the suitability evaluation index system according to its principles. Defined by the suitability classification standard with Analytic Hierarchy Process(AHP), the area with more than 80 total score of suitability was determined as the most suitable area. The area with between 80 and 60 total score of suitability was determined as the suitable area. The area with between 60 and 40 total score of suitability was determined as sub-suitable area. The area with less than 40 total score of suitability was determined as unsuitable area. It provides a scientific theory base and decision support for reasonable layout of the household biogas and biogas eco-agricultural model.
