【摘要】 中国乡村发展进入转型发展的关键时期，呈现更加复杂和多元化的发展态势。乡村聚落的用地类型与空间布局是推进乡村振兴急需解决的关键科学问题。蒙东农牧交错区自然地理格局复杂、经济地理区位特殊，但该区域乡村聚落的空间演变规律及其驱动机理研究不足。本文基于1990年、2000年、2010年和2020年4期蒙东地区土地利用数据，借助GIS空间分析和地理加权回归等方法分析乡村聚落空间演变及其影响因素。结果表明：(1)蒙东地区乡村聚落规模差异显著，微、小型聚落居多。(2)乡村聚落核密度的空间分布非常相似，具有“南密北疏”的分布特征。(3)乡村聚落的规模和密度分布具有负相关的局部特征，聚落具有高密度-小规模集聚和低密度-大规模集聚的特征；(4)乡村聚落空间分异受自然和人文综合影响，空间差异显著。其中，人口密度和人均耕地面积呈正相关；距河流距离和乡村人口比重呈负相关；人均大家畜数量正负作用均存在，区域差异显著。研究结果可为内蒙古农牧交错区乡村聚落空间格局的优化及乡村振兴战略的实施提供科学依据。更多还原

【Abstract】 Rural areas in China have entered a critical phase of transformation and development, presenting a more complex and diversified development situation. Land-use types and spatial layout of rural settlements is a key issue that urgently needs to be addressed for promoting rural revitalization, particularly in some of geographic transitional zones in China. The agricultural-pastoral transition regions in the eastern Inner Mongolian Plateau of China, characterized by their intricate natural geographic patterns and special economic and geographic locations, had not received sufficient research attentions by scholars particularly to rural settlements-related subjects. In this study, it analyzed the evolution pattern and influencing factors of rural settlements in eastern Inner Mongolia based on four periods of land-use data of 1990, 2000, 2010 and 2020. GIS spatial analysis, Geographically Weighted Regression models, etc. were used to interpret the data. It found that(1) there were significant differences in the scale of rural settlements in eastern Inner Mongolia, with the majority being micro and small size settlements.(2) By the spatial distribution of Kernel density, rural settlements had a high similarity in regional layout, with a pattern of “intensive in the south and dispersal in the north”.(3) There was a negative correlation between the scale and the density distribution of rural settlements. It exhibited a pattern of small-scale agglomerations characterized by high density and large-scale agglomerations characterized by low density.(4) The spatial differentiation of rural settlements were influenced comprehensively by natural factors and human factors, and it was significant; Among them, population density and per capita arable land were positively correlated; The distance from rivers and the proportion of the rural population were negatively correlated; The number of large livestock per capita had both positive and negative effects, with significant regional differences.The research results provide a scientific foundation for optimization of spatial pattern of rural settlements and implementation of strategy of rural revitalization in the agricultural and pastoral areas of Inner Mongolia.更多还原
