摘　　要：为更好地理解地形地貌特点和变化,文中使用C#编程语言以及Arc Engine(AE)开发组件设计并实现了坡面地形特征提取系统,可完成坡度坡向等地形因子的自动提取。以庐山地区的实际DEM数据为基础与Arc Map软件进行对比验证,实验显示提取结果完全相同,效率相较于ArcMap有所提高,并且可进行基于DRAGUT原则的微观地貌分类,分类结果清晰明确。In order to better understand the features and changes of the terrain,in the paper,slope terrain feature extraction system was designed and realized using C# language and Arc Engine (AE) components to complete the automatic extraction of terrain factors such as slope and slope.Based on the actual DEM data of Lushan area,the results were compared with Arc Map software. The results showed that the extraction results were identical,the efficiency was improved comparing with ArcMap,and the micro-geomorphology classification based on DRAGUT principle could be carried out. The classification results were clear.
