摘要
本文根据国内外在地理信息系统方面的进展，就地理信息系统的科学概念、基本构成和它的以下一些发展趋势作了讨论：（1）地理信息系统是构成地理学日臻完善的技术体系的重要部分；（2）空间分析功能是系统研究和应用的主要目标；（3）系统最重要的技术问题是管理和存储大量空间数据的数据结构；（4）综合性的发展特色日益明显；（5）标准化和智能型的发展方向已引起关注。

Based on the progress of geographic information systems (GIS) in different countries, the
definition and basic components of a GIS were involved, and five trends relating to the deve-
lopment of GIS were discussed. These trends are as follows:
1. The GIS has become an important component of a being perfected technical system
applied to geography;
2. To perform various types of spatial analysis represents a major aim in applications
and research of GIS;
3. The most important technical topic within the field of GIS concerns the spatial data
structures;
4. The integration of approaches and procedures within a single system is becoming in-
creasingly evident;
5. A great attention has been paid to the research on the standardization and artificiai in-
telligence techniques.
