摘　　要：空间碎片对航天器的安全具有巨大的威胁,且其数量随着人类航天活动的开展仍在高速增长,空间碎片对太空的污染已经成为一个引人瞩目的环境问题。空间碎片信息源的不断丰富以及研究的进一步深入,对碎片信息的管理和共享机制提出了迫切的要求。因此,建立一个开放的、易于管理和使用的小空间碎片数据库,实现数据的集成共享和规范管理是十分必要的。论文从系统的体系结构、软硬件配置、数据库结构和系统的功能实现等方面,阐述了基于3层B/S计算模式的小空间碎片数据库管理系统的设计和实现。系统运行稳定可靠,具有良好的可扩充性和维护性。该库的建立为空间碎片的研究、防护和数值建模提供了良好的数据服务,使碎片数据得到了充分而广泛的利用,进一步丰富了关于空间碎片的知识。The space debris is very dangerous to the security of spacecraft,and its number is increasing at speed with the expansion of humans' space exploration.Space debris has become a serious space pollutant noticed by many as-tronomers.The increase of space dust sources and the development of research about space dust are urging the need of space dust data sharing and exchanging.It is necessary for us to establish the Space Dust Database to realize the shar-ing and canonical management of data.The Space Dust Database(SDD)management system,which based on the3-layer B/S computer mode,is designed and implemented in this paper.The system's features include significantly improved runtime efficiency,a good scalability and maintainability.It is easily and expediently visited by guests.The Space Dust Database can provide some scientific bases for the study on the chemist composition,mineral composition,origin and sources of space dust,as well as provide excellent data service and decision-making support for the protection and the model construction of space dust.It is useful to improve the rate of data using and enrich the knowledge of space dust.
