数据挖掘技术在防洪决策支持系统中的应用

数据仓库能把整个部门的数据，无论其地理位置、格式和通信要求，统统集成在一起，便于最终用户访问并能从历史的角度进行分析，最后做出战略决策。数据挖掘技术可从大量数据中发现潜在的、有价值的及未知的关系、模式和趋势，并以易被理解的方式表示出来。通过论述基于数据仓库的数据挖掘技术，以及建立防洪决策支持系统数据仓库，探讨了数据挖掘技术在防洪决策支持系统中的应用。把数据仓库和数据挖掘技术应用到防洪决策支持系统中，不但在理论和实践上是可行的，而且扩大了防洪决策支持的内涵和外延，因而具有广阔的应用前景。

Application of Data Seeking Technology in Flood Control Decision-Making Support System

Data bank, no matter what its requirements for geographical position, format and communication, can integrate all the data of a department together, making analysis from historical point of view for final users convenient and working out a strategic decision. The technology of data seeking can find potential, valuable and unknown relationship, mode and tendency from a vast amount of data and express them in an easy way. Through discussion on data seeking technology of data bank and establishment of a data bank for flood control decision-making support system, the paper approaches the application of data seeking technology in flood control decision-making support system. Applying data bank and data seeking technology into flood control decision-making support system not only is feasible in theory and practice, but also enlarges the contents and extension of flood control decision-making support. Thus, it has a vast range of prospects for application.
