2.1.4 DEM data
The Digital Elevation Model (DEM) data were obtained from the Geospatial
Data Cloud (https://www.gscloud.cn/), specifically the SRTMDEM 90m
resolution raw elevation data in TIFF format. In this study, we utilized
the slope, slope direction, and focus statistics, as well as the raster
calculator tools of ArcGIS 10.8 software, to generate the slope, slope
direction, and topographic relief data for the study area, respectively.
