摘要
基于2020年土地利用、高程和坡度数据,运用平均最近邻比率、核密度估算、全局聚类检验及热点探测等方法揭示新疆乡村聚落空间分布特征与规模特征并探讨其空间分布影响因素。结果表明:(1)新疆全域乡村聚落在空间分布上集聚态势明显,南疆集聚态势高于北疆,兵团各师(市)集聚态势高于地州。(2)乡村聚落分布核密度南疆大于北疆,地州乡村聚落密度明显高于兵团。(3)乡村聚落整体空间分布呈“北疆各地州大规模-高密度、南疆各地州小规模-高密度”“北疆各师(市)大规模-高密度、南疆各师(市)小规模-低密度”特征。(4)乡村聚落分布与道路、河流的距离呈强烈的正指向性,与海拔、坡度呈负指向性。相较于新疆地州聚落,兵团聚落更趋向低海拔分布且更加依赖于交通。
Based on the 2020 land use data,elevation and slope data,the average nearest neighbor,kernel density estimation,Getis-Ord General G and Getis-Ord G*i were used to reveal the spatial distribution characteristics and scale characteristics of rural settlements in Xinjiang and explore the factors influencing their spatial distribution.The results show that:(1)The spatial distribution of rural settlements in Xinjiang is obviously clustered,with the clustering tendency of southern Xinjiang being higher than that of northern Xinjiang;the clustering tendency of each division and city of the Xinjiang Production and Construction Corps(XPCC)is higher than that of the prefectures;(2)The density of rural settlement distribution is greater in southern Xinjiang than in northern Xinjiang,and the density of rural settlements in the prefectures is significantly higher than that of the XPCC;(3)The overall spatial distribution of rural settlements is characterized by“large scale and high density in the northern Xinjiang,small scale and high density in the southern Xinjiang,large scale and high density in the northern Xinjiang divisions(cities),and small scale and low density in the southern Xinjiang divisions(cities)”;(4)The distribution of rural settlements has a strong positive directivity with the distance from roads and rivers.It has negative directivity with altitude and slope.Compared with the settlements in Xinjiang,the XPCC settlements are more inclined to low altitude distribution and more dependent on traffic.
