【摘要】：梵净山地区地属喀斯特山区,其核心区为国家级自然保护区,村庄规划布局的制约因素较多。为实现农村居民点的空间优化,综合评价了农村居民点的空间位置、自然资源和区位条件对农村居民点分布的影响,利用主成分分析法综合各影响指标,求出农村居民点规模值,在此基础上通过基于断裂点的加权Voronoi图分割其作用范围,结合"居住场势"分类,找出需要搬迁的农村居民点。结果表明:1研究区共有农村居民点23 046个,面积14 342.78 hm~2,居民点多沿道路支线和河流分布于山间河谷地带,布局散乱。2区域内有零星居民点7 871个,面积为2 641.75 hm~2,占18.42%;需保留居民点10 288个,面积为5 680.46 hm~2,占39.6%;中心居民点4 887个,面积为6 020.57 hm~2,占41.98%。3空间布局优化后的农村居民点共15 175个,总面积不变,主要应将西部和梵净山保护区内的零散聚落向东部水源充沛、交通发达的集镇地区搬迁。研究成果可为梵净山地区新农村规划的科学编制提供理论参考。
[Abstract]:The Fanjingshan area is a karst mountain area, and its core area is a national nature reserve. In order to realize the spatial optimization of rural residential areas, the effects of the spatial location, natural resources and location conditions of rural residential areas on the distribution of rural settlements were comprehensively evaluated. The scale of rural residential area is obtained. On this basis, the range of action is segmented by weighted Voronoi diagram based on breakpoints, and the rural residential areas that need to be relocated are found by combining with the classification of "residential field potential". The results showed that: (1) there were 23 046 rural residential areas in the study area, with an area of 14 342.78 hm~2, and distributed along the road branches and rivers in the mountain valley. 2 there were 7 871 scattered residential areas in the study area. The area of 2 641.75 hm~2, was 18.42; 10 288 settlements need to be reserved, with an area of 5 680.46 hm~2, accounting for 39.6%; There are 4 887 central residential areas, with an area of 6 020.57 hm~2, accounting for 15 175 rural settlements after the optimized spatial layout of 41.98.3. The total area remains unchanged. The scattered settlements in the west and Fanjingshan protected areas should be replete with abundant water sources in the east. The well-traveled market towns were relocated. The research results can provide a theoretical reference for the scientific compilation of the new rural planning in Fanjingshan area.
