在分析国内城市环保信息化现状的基础上,对基于组件式GIS的城市环保信息系统进行了整体设计,探讨了系统的总体结构、数据组织和功能设计,阐述了系统的开发环境、元数据和系统集成等关键技术.以扬州市为例,建立了扬州环保信息系统,包括环保GIS基础信息共享平台和污染源管理子系统,实现了环境信息的空间化、可视化管理,以及沿河污染源分析、河流水质预测等一系列高级分析功能,为扬州市环境保护工作提供了科学的决策依据.

Through analysis of present situation of Informational Construction in Urban Environmental Protection Bureaus of China, the Urban Environmental Protection Information System based on ComGIS is designed in this paper. Key technologies such as data organization and functionality designation are studied, and development environment and integration technology are analyzed. Through analyzing the characteristics of environmental management of Yangzhou city, and establishing urban environmental geo-spatial data base and attribute data base, Yangzhou Environmental Protection Information System was developed based on comGIS, including Fundamental Map module, Accessing Data module, Geometry Object module, Output module, etc, as well as Fundamental Platform for Information sharing and Pollution Managing Subsystem. It realized visualization in managing information about environmental protection, and provided scientific supports for Yangzhou environmental management.
