【摘要】 在上世纪的最后二十年，世界各国已经成功地利用信息技术、遥感探测技术、可视化技术、系统仿真技术来研究地面环境，帮助人类认识、分析和利用环境，从而为人类的活动提供辅助决策。随着人类活动范围的扩大与航天活动的增强，空间环境的研究也越来越被人们所重视。正像研究地面环境一样，空间环境是人类科学发展的下一个焦点，开展空间环境及其效应的研究，从中掌握和发现其活动规律，可以为人类利用和进入空间奠定坚实的基础。 本文通过对空间环境要素建模、可视化仿真、分布式交互仿真、数字地球等相关技术的深入研究，创造性地将系统仿真、空间信息系统的理论与方法应用于空间环境科学研究，提出了空间环境信息系统的概念，在此基础上建立了空间环境要素建模与仿真的技术框架，重点研究并实现了空间环境要素及其效应的三维建模与可视化仿真。同时基于仿真重用、模块开发的思想，利用高层体系结构HLA(High Level Architecture)技术详细设计了“空间环境仿真平台”联邦，重点开发了“空间环境要素仿真”联邦成员。该联邦的设计与建立为空间科学的研究提供了统一的环境背景和技术开发的仿真平台。本文的创新性工作具体包括以下几个方面： 1．按照联邦开发和执行过程模型FEDEP(Federation Development and ExecutionProcess Model)，通过对“空间环境仿真平台”的功能分析，设计了“空间环境仿真平台”联邦，具体设计并实现了基于HLA的“空间环境要素仿真”联邦成员。通过对联邦成员开发流程和运行流程的深入研究，利用面向对象技术分析了“空间环境要素仿真”联邦成员的构成，设计了对象关系结构图，建立了该成员的仿真对象模型SOM(Simulation Object Model)表，利用KD-Fedwizard工具生成了“空间环境要素仿真”联邦成员。 2．提出了“空间环境信息系统”SpenIS(Space environment Information System)这一崭新概念，建立了SpenIS系统的基本理论，设计了该系统的技术框图和实现途径，讨论了系统中多维动态空间环境模型、空间环境的时空语义模型和空间环境信息的传输模型，探讨了地理信息系统GIS(Geographical Information System)与SpenIS结合的基础和方式，提出了几种适合于SpenIS开发的方法，并初步建立了空间环境数据库。引入“数字空间”的概念，利用SpenIS将研究对象和范围由地面目标和近地环境扩展至整个日地空间目标和空间环境，将“数字地球”、“数字空间”、GIS等概念和方法引入到空间环境研究中。 3．设计并实现了空间环境要素数据场的几何建模Spen-GBM(Space Environment更多还原

【Abstract】 During the last twenty years in the past century, most countries had already made a great success in studying ground environment by information technology, visualization technology and the systemic simulation, and assisting people in understanding, analyzing and utilizing the ground environment, and furthermore, offering assistant decisions and solutions for the human activity. With the extending of human activity scope and the enhancing of the space mission, the study on the space environment has been paid more and more attention. Being the same as the ground environment, the space environment is the essential facter for space science research. So it is the base for the human beings to use and enter into the space in investigating the space environment and the space environment effection, and discovering and understand its rules through investigation.On the base of the deep investigation in the space environment elements modeling, the visualization simulation, the distribution interactive simulation, the digital earth technology and so on, in the thesis we had creatively applied the theory and methods of the systemic simulation and the space information system to the space environment research, and advanced the space environment information system (SpenIS) concept. Baed upon SpenIS, we set up the technology framework for the space environment elements modeling ang simulation, emphasized the space environment elements and its effection 3D modeling ang visualization simulation. At the same time, based on the simulation repetition and the module development idea, we gave out a detailed design scheme on the "the space environment simulation platform" federation and focused on the exploitation of "the space environment elements simulation" federates, which provide a uniform space environment setting and technology development simulation platform for the space science research. In this thesis, our main creative research jobs comprise the following parts:1. The "space environment simulation platform" federation is designed according to the FEDEP (Federation Development and Execution Process Model) and the function analysis on the "space environment simulation platform". A detailed designment and realization scheme is given on the "the space environment elements simulation" federates based on HLA. Based on the research of the federates development and running flow and a deep analysis on the configuration of "the space environment elements simulation" federates with the Object Oriented Model technique, an object relation structure figure is designed for the federates and also a Simulation Object Model (SOM) table is set up for it. Moreover, the "space environment elements simualtion" federates is constructed by KD-Fedwizard tool.2. A new conception of the "space environment information system" (SpenIS) is put forward, and its fundamental theory, technical framework and realization approaches are also founded in the paper. Additionaly, further discussion is given on its multi-dimensional dynamic space environment model, the space-time spatial enviroment model and the space environment information transmission model. According to the exploration about the unified basis of the GIS and SpenIS technologies, some applausible realiation schemes are brought forward for SpenIS and a preliminary space enviroment database is built. Compared with "the digital earth" and "the digital space", the SpenIS expanded the research object and contents from the ground objects to the entire sun-earth space objects and environment and creatively applied更多还原
