摘要
本文是基于陕南地区ASTER GDEM2的30m分辨率的DEM数据,在ArcGIS中提取多种窗口下的地形起伏度数据,采用均值变点法确定最佳邻域分析单元。对陕南地区的起伏度、坡度、坡向、海拔以及水土保持地形因子进行定性定量分析。该研究所提供的基础数据以期为该地区的农业生产、工业布局、规划建设以及环境保护提供理论依据。
This paper is based on THE 30M DEM data of ASTER GDEM2 in southern Shaanxi,topographic relief data under various Windows were extracted in ArcGIS,and the mean point variation method was adopted to determine the optimal neighborhood analysis unit.The topographic relief,slope,slope direction,altitude and soil and water conservation topographic factor in southern Shaanxi is analyzed qualitatively and quantitatively.The basic data provided by this study is expected to provide a theoretical basis for southern Shaanxi in agricultural production,industrial layout,city construction,and environmental protection.
