舒城县农村居民点适宜性分析

Rural Residential Layout Suitability Analysis and Optimization Countermeasures in Shucheng County

以安徽省舒城县为例,构建居民点适宜性评价指标体系,综合利用空间分析和聚类分析等技术方法,探究适宜性分布状态。研究发现:(1)舒城县农村居民点布局适宜性等级整体较高,但区域差异较为明显,分布具有较高的地形指向和经济指向。居民点适宜性呈较强集聚格局,热点区分布表现为由舒城县中心城区四周呈梯度衰减,具有较强的稳定性和连续性,冷点区集中于晓天镇、五显镇、三七镇等外围山区;(2)通过聚类分析将行政村划分为4个类别,第1类占总行政村数量的31%,该类别居民点适宜等级较高,第2类占总行政村数量的23%,第3类占27%,第4类占19%,该类地区短板效应明显,在整治中需要有针对性改善。

Taking Shucheng County in Anhui Province as an example, taking the administrative village as a unit, by selecting 11 factors such as rational structure, production support, convenient life and reasonable space, using the spatial analysis to obtain the suitability of the settlements in each villageand then adopt the cluster analysis divides the residential suitability category, finally puts forward the reasonable optimization layout suggestion according to different categories. The findings are as follows： （1）The suitability distribution of settlements in administrative villages throughout the county shows the spatial heterogeneity pattern of ＂mezzanine＂with northeast and central high, low southwest and dense areas. （2）The administrative villages are divided into four categories by cluster analysis, and the four categories are analyzed and evaluated respectively. （3）According to the different categories, we proposed the three kinds of development modes of moving the village and developing the characteristic industry mode, optimizing the mode of the merger and developing center village, and retaining the potential urbanization mode. The results can provide reference for the suitability analysis and layout optimization of rural residential areas in China.
