摘要
开展乡村聚落时空分布格局演变特征及影响因素探究,对推进乡村振兴战略具有重要的理论价值和实践意义。本文以2000、2010、2020年3期土地利用数据为基础,综合运用景观格局指数、平均最近邻指数、核密度分析和空间热点探测方法,揭示阿勒泰地区2000—2020年乡村聚落的时空演变规律,探索乡村聚落空间格局演变原因。结果表明:(1)在时间上,近20 a阿勒泰地区乡村聚落斑块个数先减少后增加,斑块面积整体呈增加趋势,斑块密度增加(增长率为2.35×10^(-6)个·hm^(-2)·a^(-1));在空间上,阿勒泰地区乡村聚落呈“西北多东南少、西北聚东南散”分布格局;(2)乡村聚落在方向上与道路、河流分布一致,向西北—东南方向演变,且聚落分布具有强烈的海拔指向,聚落的个数和面积随着坡度增加均呈现减小趋势;(3)研究区内大部分地区呈“小规模—高密度”及“大规模—低密度”集聚分布,20 a间集聚程度先减弱后增强。通过对阿勒泰地区乡村聚落的演变特征进行分析,并对该区域演变因素进行分析,为阿勒泰地区乡村发展与规划提供参考依据。
It is of great theoretical value and practical significance to carry out the research on the evolution characteristics and influencing factors of the spatial and temporal distribution pattern of rural settlements for promoting the rural revitalization strategy.Based on the land use data in 2000,2010 and 2020,this paper comprehensively uses the landscape pattern index,the nearest neighbor index,kernel density analysis and spatial hotspot detection methods to reveal the temporal and spatial evolution of rural settlements in the Altay Perfecture from 2000 to 2020.Exploring the reasons for the evolution of spatial pattern of rural settlements.The results show that:(1) In the past 20 years,the number of rural settlement patches in the Altay Prefecture first decreased and then increased,the patch area showed an overall increasing trend,and the patch density increased(the growth rate was 2.35×10^(-6)/(hm^(2)· a));spatially,the rural settlements in the Altay Perfecture have a distribution pattern of “more in the northwest and less in the southeast,gathering in the northwest and spreading out in the southeast”;(2)The direction of rural settlements is consistent with the distribution of roads and rivers,and evolves from northwest to southeast,and the distribution of settlements has a strong elevation orientation,and the number and area of settlements show a decreasing trend with the increase of slope;(3)Most of the areas in the study area showed a "small-scale-high-density" and "large-scale-low-density" agglomeration distribution,and the agglomeration trend increased first and then decreased during the 20 years.By analyzing the evolution characteristics of rural settlements in the Altay Prefecture and analyzing the de-evolution factors,it can provide a reference for the rural development and planning in the Altay Prefecture.
