摘　　要：选择典型的闽南山区县安溪为研究区域,以2021年landsat8_oli遥感影像和DEM为数据源,采用ERDAS提取乡村聚落点,利用GIS空间分析、缓冲区分析等方法,研究安溪县的乡村聚落分布特征,并对其空间分布特征的主要影响因素的影响机理进行探讨.结果表明,安溪县乡村聚落分布呈现“东南密,西北疏”“块状集聚,小块连成带状,分布不均”;其分布特征受交通、河流、高程和坡度影响较大.Selecting Anxi County,a typical mountainous county in southern Fujian,as the research area,using the 2021 Landsat8-oli remote sensing image and DEM as data sources,ERDAS was used to extract rural settlement points.GIS spatial analysis,buffer zone analysis,and other methods were used to study the distribution characteristics of rural settlements in Anxi County,and the main influencing factors of its spatial distribution characteristics and their influencing mechanisms were explored.Research has shown that the distribution of rural settlements in Anxi County is dense in the southeast and sparse in the northwest,with blocky clusters,small blocks connected into a belt,and uneven distribution;its distribution characteristics are greatly influenced by traffic,rivers,elevation,and slope.
