基于RS和GIS的黄山花岗岩砂化与地形因子的关系研究

Study on Relationship between Weathering Granite and Terra in Factorsin Huangshan Mountain Based on RS and GIS

基于RS、GIS的技术和数字高程模型（DEM）,揭示黄山风景区花岗岩砂化的空间分布,探讨花岗岩砂化与地形因子的关系。结果表明,花岗岩砂化主要分布于海拔900～1 100 m,坡度在30°～50°之间,剖面曲率25以下,平面曲率在60以上,坡向朝北的区域。

Based on RS, GIS technology and digital elevation model （DEM）, spatial attribution of weathering granite in Huangshan Mountain is revealed, and the relationship between weathering granite and terrain factors is discussed. It shows that the elevation of weathering granite mainly distributes from 900 m to 1 100 m, the slope is from 30 degrees to 50 degrees, on a northwest slop region with profile curvature below 25 and plane curvature above 60
