环境模型库与地理信息系统的耦合

针对基于GIS开发的环境信息系统多数存在环境专题分析能力不强与环境专题模型缺乏有效的整合和协同运行的问题 ,建立了一个基于面向对象的环境模型库 ,并耦合在GIS的平台之上 ,有效地对环境模型进行管理与选型 ,利用GIS的空间优势直观地分析解决环境问题 ,从而为环境信息系统增加新的强大功能。最后以区域大气环境管理决策支持系统的研究与开发为例子介绍了其框架结构和应用情况。

Integration of Environmental Model Base with Geographical Information System

In allusion to the weakness of analytical ability of environmental information system (EIS) based on geographical information system (GIS) in some environmental issues and the shortcoming of environmental model which cannot integrate efficiently and work together smoothly, this paper built an oriented-objective environmental model base (EMB) integrating into GIS, which was efficient in managing and selecting environmental model and solving environmental issues. Finally the structure and application was introduced, taking regional air environment management decision-making system as an example.
