| 摘 要： | 利用研究区地形图制作数字高程模型(DEM)并由DEM派生出坡度、坡向图。通过DEM与坡度、坡向图的叠置分析，以确定徂徕山地形因子与侵蚀类型及侵蚀过程的关系．研究结果表明：徂徕山区域土壤侵蚀方式具有明显的垂直分带性。不同坡向的侵蚀强度有明显差异，同时坡度不同引起的主要土壤侵蚀类型存在差异。

| Abstract: | Digital Elevation Mode (DEM) was made by relief map of the researched area, and slope and aspect were computed from the DEM. Through overlapping the DEM, slope and aspect, relationship among divisor, erosion type and erosion course was determined. The conclusion was that the types of soil erosion had obviously vertical distribution in Culai area. Different aspects made erosion intensity diverse obviously, and different ranges of slope led to diversity in the main soil erosion types. |
