1990—2020年攀枝花市乡村聚落格局动态研究

Dynamic Changes of Rural Settlement Pattern in Panzhihua City from 1990 to 2020

我国目前迫切需要掌握乡村聚落发展的时空规律,为实现乡村振兴提供数据与科学支撑。文章运用景观格局指数、核密度统计、缓冲区分析、高低聚类分析、热点探测分析方法,研究1990—2020年攀枝花市乡村聚落格局动态变化,并分析影响其变化的主要影响因素。结论如下:攀枝花乡村聚落规模增速呈阶梯式,空间上集聚度增强,形态逐渐复杂且破碎化;其动态变化受自然地理、区位条件、社会经济、政策制度多因子共同作用。

At present,China urgently needs to grasp the temporal and spatial laws of rural settlement development,so as to provide data and scientific support for the realization of rural revitalization.The paper uses landscape pattern index,nuclear density statistics,buffer analysis,high and low cluster analysis,and hot spot detection analysis methods to study the dynamic changes of rural settlement patterns in Panzhihua City from 1990 to 2020,and analyze the main influencing factors that affect their changes.The conclusions are as follows:Panzhihua rural settlement scale growth is stepwise,spatial agglomeration increases,and the form is gradually complex and fragmented;its dynamic changes are affected by multiple factors such as natural geography,location conditions,social economy,and policy systems.
