摘　　要：越野机动区域通行性分析对于辨别机动走廊，规划行进路线，划定区域范围具有重要意义，是地形分析中的一项重要研究内容。本文首先在探讨国内外越野机动区域分析现状的基础上，提出了数字越野机动区域通行性分析流程，详细阐述了其关键技术方法，即单要素层通行性分析和图像形态学处理：单要素层通行性分析包括地貌层、水域陆地层、居民地及附属设施层、植被层；图像形态学处理包括膨胀、腐蚀、填充和属性特征分析。然后对本文提出的方法进行实验验证。结果表明，该方法可行、有效，为越野机动区域通行性分析提供了一种新的数字处理途径。As significant research content in terrain analysis, trafficability analysis of cross-country maneuver zone is very important to maneuver corridor identification, plan approach route planning and partition zone designation. Based on current anal- ysis of cross-country maneuver zone at home and abroad, the trafficability analysis process of digital cross-country maneuver zone is proposed, and two key technological methods are described in detail： single element layer trafficability analysis and image mor- phologic prt^cessing. The former includes analysis of geomorphic layer, water area and land layer, habitation and auxiliary instal- lation layer and vegetation layer, while the latter includes image expansion, erosion, filling and attribution feature analysis. Fi- nally, an experiment is conducted to test the method and the results show that it is practical and effective, and can provide a new digital processing approach to trafficabilhy analysis of cross-country maneuver zone.
