灌区灌溉用水管理决策支持系统总体设计

在分析灌溉用水管理主要内容和决策流程以及确定的系统开发原则基础上,提出了具有系统结构合理、软件设计先进、实用性强、扩充性能好、适应实时决策要求的灌溉用水管理决策支持系统总体设计方案以数据库和知识库作为信息基础,以模型库作为管理决策的重要支撑手段,针对以上三库相互之间在概念和结构上存在交叉,在运行中存在数据流交换的特点,建立总控系统。通过多组件之间的接口集成整个决策支持系统,实现信息查询、灌水预报、水量分配等功能。该系统界面友好、直观,操作灵活、方便。

Framework and Design of Decision Support System for Irrigation Water Management in Irrigation District

Based on the analyses of main content and decision-making procedures of irrigation water management, a framework-design for developing the irrigation water management decision support system (IWMDSS) has been proposed featuring with an appropriated system structure, advanced software design, excellent problem-solving abilities, good extensibility and compatibility to keep up with technical changes, and suitability for an efficient and flexible real-time decision-making. The paper outlines an approach and some guidelines for developing irrigation water management decision support system .To build IWMDSS effectively, some key-techniques including GIS, graphical user interface, model management, and other advanced human-computer interaction were also addressed.
