| 摘 要： | 将GIS技术、网络技术及多媒体技术引入城市投资环境咨询与决策领域,研建武汉市投资环境咨询系统W(IECS)。WIECS针对不同用户对象有不同功能目标;系统建立需解决三大关键技术:数据库设计,包括文本库、要素库、评价结果库、方案库、模型方法库和空间信息库的设计及其整合;系统集成,基于CS/结构进行集成,使得信息从单向流动变为双向互动;分析模型及可视化技术,WIECS作为咨询分析与辅助决策支持工具,可提供良好的数据处理分析与建模工具,并实现分析与评价的可视化。根据系统功能目标,技术路线上采用GIS、Internet、Intranet及多媒体可视化等技术进行系统集成,建立图文库一体化的系统WIECS。

| Abstract: | Introducing GIS,network technology and multimedia technology into urban investment environment consultation and decision-making,and researching the construction of Wuhan Investment Environment Consultation Information System(WIECS).WIECS had different functions and aims facing different users.3 key technological problems needed to be solved when establishing WIECS:(1) DB design,including text DB,element DB,evaluation result DB,scenario DB,model and method DB and spatial information DB and their integration.(2) System integration,which was realized based on C/S structure and changed one-way information flow into dual-way.(3) Analytical models and visualization tools were supplied to make WIECS able to be applied more effectively in consultant analysis and acting decision-making support tool.To realize the WIECS'functions,GIS,Internet,Intranet multimedia visualization and other techniques were integrated in the system. |
