世纪之交地理信息系统的理论与应用发展

Development in Theory and Application of Geographic Information System at Turn of the 21st Century

本文重点概述了地理信息系统30多年来的应用和发展,简要地介绍了GIS软件技术的进步和世纪之交深化地球信息机理、自组织、自相关理论和时空专题高维数据模型以及以GIS为核心的综合集成技术体系的研究.同时讨论了新世纪信息时代与网络世界,在“信息高速公路”、“数字地球”等高新技术迅猛进程中,对GIS的深化应用研究,应纳入国家信息技术发展计划,使GIS深层次、全方位地服务于国家可持续发展和全球变化的研究等.

This paper highlights the application and development of geographic information system in the past more than thirty years, briefs the progress in GIS software technique, introduces the deepening of the geo-information mechanisms, self-organization, self-correlation theory and temporal-spatial thematic high dimensional data model as well as studies on comprehensive integrated, technical system centered around GIS at the turn of the 21st century.It also discusses information times and network world in the new century and points out in the rapid development of high &'~ new technologies such as 'information expressway' , digital earth' , in-depth study and application of GIS should be included into the State information technology development planning, make GIS offer deepening and all-directional service to the national sustainable development and global change studies.
