| Abstract: | 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. |
