| 摘 要： | 数字高程模型(DEM)是地貌解译有力的辅助工具,同时也是对地形地貌分析研究进行量化表达的一个重要手段。在前人研究的方法上通过对研究区台湾地区的SRTM-DEM数据的处理,运用GIS空间分析和统计方法进行地形分析,并在此基础上完成对地形起伏度、坡度、坡向、高程等地形因子相关的拓展分析。根据分析结果对该地区的地貌形态特征进行总结。

| Abstract: | Digital elevation model(DEM) is a powerful auxiliary tool in landscape interpretation,but also an important means of expression in terrain analysis.By the SRTM-DEM data processing based on methods of previous studies,use methods like GIS spatial analysis and statistical analysis to analyze the terrain,and then finish the expansion analysis of topography based on the factor of relief amplitude,slope,aspect,elevation.summarize the topographic feature of the region. |
