中文摘要：

动态地形仿真主要研究动态地形和军事系统之间的相互作用,这些作用直接影响着作战仿真过程和结果的逼真度和可信度。从动态地形仿真需求与原理出发,研究了动态地形仿真的两个关键技术：时序一致性和多态一致性,并基于综合环境数据表示与交换规范（SEDRIS）和高层体系结构（HLA）技术设计实现了一个动态地形仿真联邦,该联邦具有动态生成弹坑、反坦克战壕和阵地等军事实体的功能,能满足对动态地形有一定要求的作战仿真。

英文摘要：

Dynamic Terrain Simulation focuses on interaction of dynamic terrain and military system, which has a direct influence on process and result of combat simulation, and can improve fidelity and credibility of simulation. The requirement and principle of Dynamic Terrain were proposed, and the time consistency and polymorphism consistency were discussed which were two critical technologies in realizing federation. Based on HLA and SEDRIS, a Dynamic Terrain federation was realized which included crater, anti-tank ditch and theater generating functions and could satisfy combat simulation that had certain requirement for dynamic terrain.
