决策支持系统与地理信息系统的集成化研究

通过村庄布局优化决策支持系统案例，着重讨论Ｔ ＧＩＳ与 ＤＳＳ的系统集成，介绍了实现 ＤＳＳ与 ＧＩＳ集成的技术，即ＧＩＳ采用独立开发的电子地图引擎，采用与ＤＳＳ相一致的数据管理工具，在较低的层面上实现统一的数据结构和规范的数据交互，从而实现地理信息库与数据库和模型库的有机链接，实现在地图上村庄信息的显示和查询，以及村庄合并搬迁后在地图上的动态变化，使用户的决策活动更直观方便。

The System Integration of Decision Support System and Geographic information System

This paper describes the system integration of DSS and GIS by the case of the Village Distribution Optimization Decision Support System, This paper also reports the technology which is used to integrate the DSS and GIS. The electronic map tool is developed in the GIS. The data management tool same as the DSS is used in the GIS. The same data structure and data interface is used in low level. The map showing and inquiring Of the village information, as well as the change of the map after the villages are moved, are based on the link between the geographic information base and database and model base. SO the users' decision result is more directed, convenience and visualized.
