以重庆市万州区为例,借助Arc GIS、Geo Da、Fragtats软件,运用探索性空间数据分析、空间韵律测度及多维特征组合方法,分析研究区农村居民点空间分布、规模和形态,探索居民点布局类型及优化路径。结果表明:(1)在空间分布上,呈“西密东稀”的分布格局;(2)在规模结构上,农村居民点间呈正的空间自相关性,但相关程度较低,西部存在多个低值集簇区,东部多随机分布;(3)离城镇、河流、交通近的区域居民点分布多,形状指标也较大;(4)通过多维度特征组合方法,将万州区农村居民点划分为18种布局形式,以中等规模-形态规整-优势区位、大规模-形态规整-优势区位为主,并从发展模式、基础建设、生态涵养等方面提出相应的优化调控路径。
Taking Wanzhou District of Chongqing Municipality as an example, using Arc GIS, Geo Da and Fragtats software, exploratory spatial data analysis, spatial prosodic measure and multi-dimensional feature combination method were used to analyze the spatial distribution, size and shape of rural settlements in the study area, Layout type and optimization path. The results showed as follows: (1) In the spatial distribution, there was a distribution pattern of “Xi-Dong Dongshen ”; (2) On the scale structure, there was a positive spatial autocorrelation among rural settlements, but the correlation degree was lower. There are many low-value clustered areas in the east, with random distribution in the east. (3) There are many residential areas in cities, rivers and near traffic areas with large shape indexes. (4) By multi-dimension feature combination method, The rural residential areas are divided into 18 kinds of layout forms, with medium size - shape regularity - superiority location, large scale - shape regularity - dominant location, and put forward the corresponding optimal regulation and control path from the aspects of development mode, infrastructure construction and ecological conservation.
