摘　　要：北方农宅供热能耗影响因素的研究可为农宅供热节能改造、国家节能政策和相关规范的制定提供有力的依据。影响农宅供热能耗的因素种类繁多,并且影响程度不同。本文运用SPSS19.0软件,采用独立样本t检验、单因素方差分析以及控制供暖系统组成形式下的双因素方差分析,进行农宅供热能耗影响因素的筛选及其影响程度的深度剖析。初步统计研究结果表明在0.05显著性水平上的农宅供热能耗主要影响因素为冬季炊事频率、所在地区、家庭常住人口数和供热系统组成形式。The research of heating energy consumption of rural building in the north can provide powerful basis for energy saving renovation and energy conservation policy and codes enaction.There are diversified factors that can affect the heating energy consumption of rural buildings.In order to select the key factors and understand its magnitude of the impacts,the analysis on the independent sample t-test and one-way as well as univariate independent samples of variance by SPSS19.0 software were utilized in the research.The preliminary result of key factors at the significance level of 0.05 is as follows：the cooking frequency in winter,geographic area,the number of family members and heating systems.
