摘　　要：以嘉陵江流域为研究对象,利用数字高程模型(DEM)数据提取坡度、坡向和高程点信息,基于流域的河流和上、中、下游社会经济情况对居民点空间分布格局及其影响因素进行定量分析。结果表明:嘉陵江流域居民点的分布特征明显倾向于分布在坡度小、阳坡、海拔低、与河流距离适中、经济发达的地区。研究结果将为嘉陵江流域居民点选址提供参考。Taking the Jialingjiang River Basin as the research object,the digital elevation model(DEM)data of the Jialingjiang River Basin was used to extract the slope,aspect and elevation information,and based on the social and economic conditions of the Jialingjiang River Basin,the spatial distribution pattern of the residential area in the Jialingjiang River Basin and the influencing factors were quantitatively analyzed.The results showed that the settlements tended to be distributed in areas with small slopes,sunny slopes,low elevations,moderate distance from rivers,and economically developed areas.The results of this study would provide favorable reference conditions for the selection of residential sites in the Jialingjiang River Basin.
