摘要
目前,由于研究领域和角度的不同,坡长的定义不尽一致,本文旨在选用满足水土保持、区域地形描述的坡长定义,设计了一种在Arc GIS中较合理的坡长提取方法,并分析了其在不同地貌类型区之间的信息差异。
Recently, the definitions of slope length in existence differ from each other because of the different fields and aspects in research. In this paper, a definition of slope length has been put forward according to water and soil conservation and regional terrain description. And the information differences have been analyzed among different geomorphologic areas and among different scale DEMs after the slope length is extracted relatively reasonably aided by ArcGIS.
