摘　　要：基于2006年1000份的调查问卷和国家统计年鉴近10年数据,统计分析了我国农村生活用能结构、用量及获取方式,提出了一种适用于我国农村的分布式供能模式,并通过估算各地风能、太阳能储量和农村家庭用能量,对这种农村分布式供能模式做了详细的供需分析。研究结果表明,我国农村生活用能结构主要包括炊事、热水、取暖、照明和文明生活用能,生活用能总量和农村用电量分别保持了4.91%和11.12%的增长速度;若分布式供能系统以每户安装1kW风力发电机和1.2m2太阳能集热来计算,全国可有57%的省份可由当地可再生能源完全满足农村居民生活用能需求,且有盈余,由此论证了分布式供能具有广阔的应用前景。Based on the investigation of rural household energy consumption among 1000 families by questionnaire meanwhile refering to lately 10 years data from statistical yearbook, the rural household energy consumption structure, amount as well as the obtaining ways are analyzed, and a more suitable energy supplying system for rural area is proposed. By estimating the wind power and solar power in every province, the supply and demand of this energy supplying mode is analyzed. Results show that rural household energy consumption consists of cooking, heating and electricity utilization, and the year＇s growth rate of total energy and electricity consumption are 4.91% and 11.12% respectively; if each family install 1 kW wind turbine andl.2m2 solar energy collection, there are 57% rural families whose household energy demand can be met by local renewable energy sources even with surplus. Therefore, the rural distributed energy supplying mode is proved to have a wide application prospect.
