摘　　要：沼气是我国农村广泛使用的一种生物能源,通过对我国农村户用沼气工程的区域适宜性研究,从而对我国农村户用沼气工程适宜性进行区域划分,是我国户用沼气工程发展的基础和前提。笔者通过对沼气使用影响因素的分析,从气候、原料、经济方面选取了7个指标,并用层次分析法确定了权重,构建了户用沼气区域适宜性评价指标体系。对我国31个省、直辖市和地区进行加权模糊聚类,根据F统计量方法确定最优阈值,得出最佳分组,最后通过插入最优和最劣对象对聚类结果进行排序,得到了我国户用沼气的适宜区域划分结果。根据最终的分类结果,对7类区域的农村户用沼气工程发展策略提出了建议。Biogas is a kind of biomass energy sources which uses extensively in the rural, through the research of rural domestic biogas project regional suitability, dividing the rural domestic biogas project suitable area is the premise and basis for the development of the domestic biogas project. Based on analyzing the influencing factors of biogas project, seven indicators were selected from climate, resources and economic aspects and AHP were used to determine the weight. Then using the weighted fuzzy clustering to the country＇s 31 regions and choosing F - statistics method to determine the optimal threshold, the best grouping for seven groups were obtained. Finally, by inserting the optimal object and the worst object to sorting the clustering result, we got the result of classification of rural domestic biogas suitable area. According to the classi- fication result, advices for rural domestic biogas project of seven kinds of region were put forward.
