GIS环境下的流域水资源优化配置模型

Water resources optimized allocation model in GIS environment

采用面向对象的方法,把流域水资源配置问题当作空间对象和专题对象的一个集合,建立一个概念GIS数据结构,将流域水资源配置模型的物理表达和逻辑表达整合到一个可操作的框架中。基于这样一个框架,扩展GIS的功能来实现GIS和流域水资源配置模型的紧密结合。这样,流域水资源配置的数据、模型和用户的交互被整合到了GIS中,能够很方便灵活的建立模型并进行分析。

With the object-oriented approach,taking basin water resources allocation as an assemblage of spatial object and special object,setting up a GIS conceptual data structure,the physical expression and logic expression of basin water resources allocation is integrated into an operable framework.Based on this framework,close combination of basin water resources allocation and GIS is realized by expanding GIS function.As a result,data,model and user exchange of basin water resources allocation are integrated into GIS,so the model can be set up and analyzed easily and conveniently.
