摘　　要：针对载人月球探测月面全空域、全时域覆盖的通信需求,对现有直连通信和几种引入中继通信的地月空间信息网络体系架构进行了仿真对比分析,最终确定了引入中继通信并融合近月空间子网和近地空间子网的地月空间信息网络体系架构为最优方案,该体系架构兼具多重月面覆盖、长时地面测控可见时间、海外建站数量少和成本相对较低等优势,可为我国未来地月空间信息网络建设提供参考。Based on the communication needs of full-time coverage of the entire lunar surface in themanned lunar exploration, the Earth-Moon Space information network of direct communication andrelay communication were comparative analyzed and simulated. As a result, an Earth-Moon Spaceinformation network architecture based on relay communication and combining with lunar Space sub-net and terrestrial Space subnet was proposed as the optimal solution. The architecture of Earth-Moon Space information network had the advantages of multiple lunar overlays, long time ground mo-nitoring and control visible time, less overseas satellite ground stations and relatively low costs,which might serve as a reference for the construction of Earth-Moon Space information network of ourcountry.
