Study on Spatial Pattern Evolution and Causes of Rural Settlement in Alxa League of Inner Mongolia
In order to explore the evolution and development of village and village settlement space in Alxa League of Inner Mongolia under complex physical geography and social system environment,based on the village and village settlement patch data from 1988 to 2023,and analyzes the evolution of the spatial pattern of village and town settlement system in Alxa League by using the spatial pattern analysis tools such as standard deviation ellipse and average nearest neighbor,and introducing the spatial growth index and rank-scale rule.The results are as fol-lows:(1)The direction of the spatial layout of settlements is gradually weakening,and the area and scope of ag-glomeration are expanding.(2)The growth rate of settlement scale is large,but the fluctuation of growth rate is al-so strong.The settlement patch changes from large-scale high-value settlement agglomeration to compound small-scale attachment to large-scale settlement agglomeration.(3)The monopoly of the first place settlement is strong,the development of the middle order settlement is slow,and the growth of the low order settlement is fast.(4)The main factors that influence the evolution of the spatial pattern of Alxa League villages and towns include the external binding force ecological factor,the centrifugal force construction factor,the decision-making force policy factor,the internal driving force economic factor and the traction force cultural factor.
