摘　　要：利用ArcGIS软件提取了研究区DEM的高程、坡度、坡向、起伏度等信息与国家1∶25万基础地理信息数据库提供的居民点、水源信息进行空间叠加分析,得出云南特有民族——独龙族居民点的空间分布与高程、坡度、坡向、起伏度、水源的定量关系,揭示了自然因素对本区居民的影响程度,为人们更好地了解独龙族所处的独特地理环境提供了依据.The data about elevation, slope, height of DEM in research area, undulant amplitude abstracted by ArcGIS software were spatially overlapped with the information of residential areas and water- shed of Dulong obtained by national geographic database with the scale of 1 ： 250000. As a result, the quantitative relationship between the Dulong residential areas and natural factors including height, slope, undulant amplitude and watershed was achieved. This revealed the extent of natural factors＇ impact on the residents in this area so as to provide a basis for better understanding of Dulong＇ s unique geographical environment
