摘 要: 简要介绍了MapObjects和Matlab的相关功能,结合南水北调(东线)水资源优化决策支持系统的建设,论述了利用Visual Basic(VB)和MapObjects(MO)混合编程编制水质评价及其可视化模块,综合运用Matlab图形显示和地理信息系统(geography information system, GIS)属性表功能,实现水质监测资料的实时查询和实时显示,同时在VB中调用Matlab函数实现水质变化的三维可视化。应用两种评价方法:一种是应用模糊数学中的模糊综合评价方法进行水质综合评价,将评价结果用专一图层的形式表示出来,对不同的水质进行颜色分级,同时运用Matlab的图形显示功能实现水质的三维可视化;另一种是应用单因子评价方法确定主要污染因子,将评级结果以GIS属性表的形式在地图上显示出来,方便用户实时查询,为南水北调(东线)的水环境质量管理和宏观决策提供技术支持。
关 键 词: 环境系统工程;水质可视化;水质评价;南水北调(东线)

Abstract: This paper briefly introduces the Matlab and MapObjects related features, combining with construction of the optimized water resources decision support system in the South-to-North Water Diversion Project (East Route),and discusses the use of Visual Basic (VB) and MapObjects (MO) mixed programming in the preparation of assessment of water quality and visualization modules. Matlab graphics and geography information system (GIS) attributes table function are used comprehensively to achieve real-time inquiry and real-time display of water quality monitoring data, at the same time, calls Matlab functions in VB to achieve the three-dimensional visualization of the water quality changes. Two methods of evaluation are applied. One is applying fuzzy comprehensive evaluation method from fuzzy math to evaluate water quality comprehensively, the results of evaluation will be expressed specifically in the form of layers in which the water quality are classified by different colors, meanwhile the Matlab graphic display function is used to achieve the three-dimensional visualization of water quality. The other one is using the single factor evaluation method to determine the major pollution factor, the rating results will be displayed in the form of GIS attributes table on the map, which is convenient for users to inquire in real-time. This research will provide technical support for water environmental quality management and macro policy-making of the South-to-North Water Diversion Project (East Route).
Key words: environmental systems engineering; visualization of water quality; water quality assessment; the South-to-North Water Diversion Project (East Route)
