摘　　要：文章运用景观生态学理论与GIS空间分析技术,以彭水县保家镇为例,对西南山区农村居民点的分布特点及其影响因素进行分析,研究表明:山区农村居民点具有布局零散,集聚度低、规模等级不明显、聚落密度地域差异大的特点,这种分布受坡度、海拔、交通、经济、耕地分布等因素的影响较大,具有强烈的低坡度、低海拔的区位取向、交通区位取向、经济区位取向,以及耕地分布的空间趋同性特点。最后提出山区农村居民点规划应坚持"集中为主,分散为辅,散中有聚"优化布局原则,同时针对保家镇农村居民点的布局给出了具体的优化方案。Based on landscape ecology theory and the spatial analysis technique of GIS,the article studies the distribution characteristics and influencing factors of rural settlements in southwest mountains regions as a case of Baojia township of Pengshui county with the major data sources of database of the second national land survey（including contour line,river,road and rural settlements）at the scale of 1：10000.The results shows that rural settlements land areas are scattered sites in disorder at present,and main influencing factors include the altitude,the degree of slope,inconvenient water,road accesses,and the distance from cultivated land.The basic layout optimization principle in land use planing that concentration,decentralization and scattered concentration should abided by in mountain regions.Some suggestions on the adjustment of the distribution of rural residential land was put forward.
