摘　　要：从地理信息系统在数字郑州管理中的应用出发,从城市公交查询系统建立的必要性出发,研究了基于组件式GIS的公交查询系统的设计。本系统选用GIS组件SuperMap Objects作为地理信息系统二次开发组件,通用语言Visual Basic 6.0作为开发工具,Microsoft Access 2000作为后台数据库,快速开发城市公交查询系统,实现了地图的放大、缩小、漫游等GIS软件的基本功能,以及公交换乘方案和地名的查询等空间查询功能。在介绍了系统总体设计、功能设计、数据库设计、界面设计及输入输出设计之后给出了系统中一些功能的实现原理与具体方法,最后展示了本系统的最后开发成果。This paper is based on the necessity of urban public traffic inquiry system, this article studies the design of the system based on component GIS,discusses the realization project of the public traffic inquiry system. The system chooses SuperMap Objects to be component of GIS secondary component,current program language --Visual Basic 6. 0 as develop tool, Microsoft Access 2000 as background database, developed rapidly urban road and traffic inquiry system. It realized basic skills of GIS software such as zoom in, zoom out and ramble, and special search skills, namely, way of bus transfer and search of place names. The paper introduced the overall design, functional design, database design and input -output interface design of digital city. Meanwhile the principles and the specific methods related are summarized. In the end, the final product of this system is displayed.
