摘　　要：以2009—2012年湖南省各市州农村户用沼气发展水平数据为研究对象,运用变异系数、泰尔指数、相对变化率及因子分析方法,借助Stata和GIS软件,研究湖南不同市州沼气发展的时空变异特征及其驱动因子。结果显示：①湖南沼气池保有总量和农村人均沼气池保有量均呈稳步增长态势;②永州市、益阳市沼气池保有量相对变化率较高,而长沙市、湘潭市沼气池保有量相对变化率很小;③湖南各市州沼气池保有量的空间差异呈逐年缩小态势;④影响各市州沼气发展空间变异的主导影响因子是规模因子、成本因子和速度因子。Based on the rural household biogas data of each city in Hunan Province from 2009 to 2012, this study presents the spatio-temporal change and driving factors of the biogas development of each city in Hunan by variation coefficient, Theil index, relative change rate and factor analysis method, combining with Stata and GIS technology. The results indicate that： Firstly, the biogas digesters number and the biogas digesters per capita in Hunan both grow steadily; Secondly, the relative change rate of digesters number in Yongzhou and Yiyang are higher, while those were lower in Changsha and Xiangtan; Thirdly, the spatial disparity of digesters number of each city in Hunan is gradually narrowed down; Finally, scale factor, cost factor and speed factor are main driving factors of biogas spatial change in each city.
