山地都市边缘区农村居民点格局演变及影响因素分析

Analysis on Pattern Evolution and Influence Factors of Rural Settlements in Mountainous Urban Fringe Area

针对农村生产生活方式发生转型,揭示山地都市边缘区农村居民点格局演变规律,对重构城乡融合背景下山地都市边缘区乡村空间有重要意义;以重庆市两江新区为例,综合运用空间分析及空间统计法探索山地都市边缘区农村居民点格局特征及影响因素;结果表明:2010—2016年农村居民点呈现大规模低密度集聚分布与小规模高密度集聚的分布特征;农村居民点核密度由四大集聚地带逐渐向“多核心”式分散布局;农村居民点整体分布向东北扩张;地形地貌、政策规划、人口、区位、交通因素对山地都市边缘区农村居民点分布格局有一定影响;研究结果可为山地都市边缘区城乡融合发展下的乡村空间重构提供参考。

Aiming at the transformation of rural production and life style,it was of great significance to reconstruct the rural space in the mountain urban fringe area under the background of urban-rural integration by revealing the evolution law of rural residential pattern in the mountain urban fringe area.LiangJiang New Area of Chongqing in China was taken as an example in this paper.Spatial analysis and spatial statistics were comprehensively used to explore the characteristics and influencing factors of rural residential area pattern in the urban fringe area of mountainous areas.Experimental results show that the total size of rural settlements decreased,the number of rural settlements was large and the scale was small,and the overall distribution density was relatively high,core density of rural settlements was gradually distributed to“multi-core”pattern from four agglomeration zones from 2010 to 2016;In spatial distribution,the rural settlements patches were characterized by agglomeration.There was a general negative correlation between the density distribution and the size distribution,indicating that the overall distribution of rural settlements showed the trend of northeast expansion,and the northeast is the hot area of rural settlements.The factors such as topography,population,policy planning,location and transportation had a certain influence on the distribution pattern of rural settlements in the urban fringe of mountainous areas.This study can provide a reference for the rural spatial reconstruction under the urban-rural integration development in the urban fringe area of the mountainous area.
