摘要:
探究农村居民点的时空演变与影响因素,以喀什地区为例,采用网格分析、核密度估计等空间分析手段,研究喀什地区2009-2019年农村居民点时空分布特征及演变规律,选取坡度、地形起伏度、人口密度、耕地面积、距道路距离、距河流距离、距最近耕地距离、增减挂钩政策8个影响因子,进行地理探测和地理加权回归(geographically weighted regression,GWR)分析.结果表明:2009-2019年喀什地区农村居民点集聚特征显著,主要集中在叶尔羌河冲积平原和喀什噶尔河冲积平原,呈现集聚中部、西密东疏的分布特征,在2019年达到核密度峰值;2009-2019年喀什地区农村居民点的数量和面积逐年增加,但农村居民点平均面积由0.011 0 km2减少至0.010 7 km2,10 a间喀什地区农村居民点演变方式为自身扩展、新生/合并和消亡;坡度、地形起伏度、人口密度、耕地面积、距河流距离、距道路距离和距最近耕地距离是影响喀什地区农村居民点空间分布的主导因子,增减挂钩政策对喀什地区农村居民点空间分布影响不明显;各影响因子对农村居民点分布的影响存在显著空间差异,距道路距离和距河流距离起主导作用.
Abstract:
To explore the spatial and temporal evolution and influence factors of rural settlements, taking Kashgar Region as an example, the spatial and temporal distribution characteristics and the evolution rules of rural settlements in Kashgar Region from 2009 to 2019 were studied by using grid analysis,kernel density estimation and other spatial analysis methods. Eight influence factors including slope, topographic relief, population density, cultivated land area, distance from road, distance from river, distance from the nearest cultivated land, increase and decrease linkage policy were selected for geographical detection and geographically weighted regression(GWR)analysis. The results showed that from 2009 to 2019, the rural settlements in Kashgar Region had significant characteristics of agglomeration, mainly concentrated in the alluvial plain of the Yerqiang River and the Kashgar River, showing the distribution characteristics of concentrated in the middle, dense in the west and sparse in the east, reaching the peak of nuclear density in 2019. From 2009 to 2019, the number and area of rural settlements in Kashgar Region increased year by year, but the average area of rural settlements decreased from 0.011 0 km2 to 0.010 7 km2, the evolution mode of rural settlements in Kashgar Region was self expansion, newborn/consolidation and extinction in the past 10 years. Slope, topographic relief, population density, cultivated land area, distance from river, distance from road and distance from the nearest cultivated land were the leading factors affecting the spatial distribution of rural settlements in Kashgar Region, the increase and decrease linkage policy had no obvious impact on the spatial distribution of rural settlements in Kashgar Region. There were significant spatial differences in the impact of each impact factor on the distribution of rural settlements, with the distance from the road and the distance from the river playing a leading role.
