摘　　要：得益于低成本火箭发射技术、微小卫星平台技术和载荷技术的迅猛发展,实现全球信息,特别是天基信息共享的天地一体化信息网络正在全世界范围内引发广泛关注。考虑到我国各类天基信息系统发展中面临的一些特殊制约条件,自主建设以天基网为核心的天地一体化信息网络迫在眉睫。它将为我国智慧城市、应急救灾、航空航天、国家安全等多个领域的发展提供必要的保障。本文在梳理了国内外相关发展现状的基础上,就我国天地一体化信息网络的基本概念提出了三点基本认识,分析了这一网络可采取的基本架构和面临的主要技术难点,并对我国天地一体化信息网络的初步建设工作提出了几点粗浅的建议。With the rapid development in the field of low-cost rocket,small and nano satellite and advanced payload,wide attention has been drawn on the integrated space-terreitrial information network,which shares global information,especially the space information. Considering some special constraints in the development of the integrated space-terrestrial information network in China,it is imminent to implement our own integrated space-terrestial network,in which the space network is the most important part.It is an enabling technology for many important fields,such as smart city,rescue and recovery in emergency,aerospace and nation security. After a review of the state-of-the-art relevant projects both at home and abroad,we give three basic arguments on developing integrated space-terrestrial network. The possible arthitecture of the network and its technical challenges are analyzed. We also give several suggestions on the initial implementation of the integrated space-terrestrial information network in China.
