面向防汛主题的信息集成研究与应用

根据防洪系统实际决策支持的需要,分析了面向防洪目标的决策主题类型与信息集成方式,应用树和图的思想表示数据结构,研究了描述各类防洪工程以及不同类防洪工程之间的拓扑关系的模型与方法;采用数据库技术、面向决策主题集成和用户界面与应用程序分离方法,建立了基于防洪工程拓扑关系的、面向防洪主题的、启发式的防汛信息服务模型.该模型融入了防洪减灾领域专家的经验与知识;在此基础上,通过应用程序的开发,实现了系统信息的快速获取与高度集成,在总体上和任一局部防洪区域内都能对防洪调度决策提供有效支持.

Study and application of facing integration method to flood control decision subject

Through the analysis of application subject and information integration manner of the flood control, according to the demand of the flood control decision support system, topological relationship between the flood control entities in various river basins is established using the thought of graphic-topology and tree-topology. Adopting the database technique, the integration method of facing the decision subject, separation method of the user interface and application program, the elicitation method of flood control information service model based on topological relationship, facing the subject of flood control is established. The model is integrated with the experiences and knowledge about the flood control accumulated by the experts and developers, and has significant realistic significance for the local and general flood control.
