水环境数学模型与GIS的集成研究

Integration of GIS and water mathematical environment model

从地理信息系统(GIS)的功能特点、环境信息的特性和水环境数学模型软件应用时存在不足的3个方面分析了GIS和水环境数学模型软件集成的必要性。介绍了GIS和水环境数学模型的集成方式以及苏州河三期综合整治决策支持系统的主要功能结构,重点从GIS和水环境数学模型集成方面介绍了地图矢量化、模型计算结果转化为相应数据库文件、数据库文件和GIS实现绑定以及断面水位动态演示的实现方法和重要作用。

Geographic information system （GIS） is a collection of computer hardware, software, and geographic data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. The benefits of integrating GIS with a water environment model are given in terms of the functional characteristics of GIS, the traits of environmental information and the potential applications. The paper presents the procedure employed for the integration and, as a case of application, the main functions and structure of the decision support system（DSS） for phase Suzhou Creek rehabilitation project. The implementation method and the significance of vector graphs, transformation of model simulations to database files, binding of database files and GIS, and dynamic display of the water level profile at a cross section at a specific time are discussed in detail and illustrated by tables and figures.
