本文首先在分析城市地理信息系统(UGIS)应用任务、专业内容和技术要求的基础上,提出了我国UGIS的研究内容及其软件发展的工具模式;接着,以GRAMS软件为例,论述了UGIS软件工具的总体结构、主要功能和技术特点;最后,还结合一些具体的应用系统,如中国城市信息系统、城市水资源信息系统以及城市环境信息系统等,介绍了UGIS软件工具的不同使用方式以及给人们带来的实际好处。

Urban Geographic Information System (UGIS) is a G1S branch with development rapid, application wide and benefit significant. The results, which got from the analysis of the applied tasks, thematic contents, technical requirements and system structure of UGIS and the comparison between the different models of software development, shows that: the development of UGIS software tools play a very important role in wide applications of UGIS in China. As one of UGIS software tools, the software structure, main functions and technical features of Geos-cience Remot sensing Application Management System (GRAMS) developed by the authors are presented. Moreover, through some UGIS applied systems, as samples, the different applied models of UGIS software tools and their benefits are described in the paper.
