中文摘要：

地形要点选取是作战指挥人员下定作战决心的一个非常重要的环节，也是军事地形分析的一个主要问题。地形要点的选取优劣影响着作战进程，甚至影响到战斗的最终结果。分析了地形要点选取指标体系结构，首次基于数字地形图，提出了地形要点选取技术途径，详述了影响地形要点选取的地形分析因子的计算方法，最后给出了实验中的地形要点选取成果以及分析与结论，结果表明该方法对选取地形要点是有效可行的，为地形要点的选取提供了一种全新的思路。

英文摘要：

The selection of key terrain is a very important process for the battle commander to make the battle decision. It also constitutes a main issue of the military terrain analysis. The selection quality of key terrain affects the battle process, even the battle result. In this paper,a selection index hierarchy of key terrain is analyzed. Originally,based on the digital map,a technique approach of the selection of key terrain is brought forward. The computation methods of the terrain analysis factors which affect the selection of key terrain are detailed. Finally,the selection result,analysis and conclusion of key terrain in an experiment are given. The experimental fruit proves the feasibility of the selection method of key terrain. This paper provides a brand-new thought for the selection of key terrain based on the digital mao.
