运用2013年长沙市的遥感影像数据，借助于空间插值、空间自相关分析以及空间变差函数等数学模型，对长沙市农村居民点的空间格局进行研究。在空间分布上，长沙市农村居民点空间布局呈现“西密东疏”的特征；在规模分布上，长沙市农村居民点的规模分布存在明显的空间随机独立性及空间分异性特征，并且出现高值聚簇区，主要分布在以浏阳市西北部的焦溪乡、淳口镇、北盛镇、山田乡等地为中心的周边区域；在形态分布上，长沙市农村居民点形态存在显著的空间分异格局，其形态分布的均质程度不高，呈现以中间区域为顶点向周边方向倾斜的结构，空间结构性差异显著，总体上呈随机独立分布状态。

Based on the satellite image of Changsha City in 2013, using spatial metric models like spatial interpolation, spatial correlation index and semivarigram, the spatial pattern characteristics of rural settlements in Changsha Changsha City was analyzed. In terms of sptial distribution, the number of rural settlements in the western part of City is more than the eastern part ; Scale distribution of rural settlements in Changsha City is characterized by a stong spatial autocorrelation and a spatial differentiation. The high value clusters of rural settlements are distributed mainly in the northwestern part of Liuyang City, such as Jiaoxi Town, Chunkou Town, Beisheng Town and Shantian Town;The shape distribution of rural settlements in Changsha City shows an obvious spatial differential pattern, but the rural settlements are not distributed evenly, which shows a structure of trend from the central area to the surroundings. The spatial structural differentiation is obvious and shows a random independence.
