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1:250000基础地理地理信息数据提供的居民点、水源信息进行空间叠加分析,得出云南省独龙江流域特有民族之一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,也为政府做好本区的民族工作提供了依据。Dulong People that live in the Watershed of Dulongjiang is one of Yunnan＇s unique People. In this paper , the elevation, slope, aspect relief amplitude information of the studying area＇s DEM were extracted by ArcGIS software. The settlements, water information were provided by National Geographic 1： 250 000 basic geographic information and data . All of these information were used for spatial overlay analysis to obtaine the quantitative relationship between the spatial distribution of settlements of Dulong People and the elevation, slope, aspect and water of the studying area. As a result, revealed the natural factors on the degree of influence of the residents in this area , the quantitative relationship not only provided the basises for a better understanding of Dulong＇s unique geographical environment but also for the government in the national work in this area.
