摘要
对灌区决策支持系统的功能进行了分析,提出了一个以地理信息系统(G IS)为中心的灌区决策支持系统的体系结构.在此基础上,构造了基于集成方式实现灌区空间决策支持系统的逻辑结构,对系统实现的关键技术、灌区干渠的配水模型,利用G IS实现的方法和模拟结果表现的方式进行了探讨.并在江苏省洪金灌区决策支持系统的开发中得到了很好的应用.
This paper analyses the function of DSS and put forward the structure of DSS in irrigation district based on GIS. And it constructs a logical structure of space DSS by integration and discusses the key technique in system implement. Based on Distributing water model of main-branch canal in irrigation district, the geographic information system (GIS) is used and the manner of representing simulative result is discussed. It has beeen used well in developing DSS of irrigation district of Hongjin in Jiangsu province.
