针对流域水文数据存在的海量、复杂、时空性等一系列特点,面向流域防洪与兴利等主题,建立了以数据层、组织层、挖掘层以及决策层为基础的流域水文数据挖掘体系,并从数据仓库、数据挖掘、元数据管理等几个方面建立了该体系的分析流程,为流域防洪和兴利业务提供了新的解决方案.将数据挖掘体系初步应用于流域的预报和调度中,证明在有充足数据的支持下,形成可行的流域预报和调度方案是合理可行的.随着数据管理、数据分析等技术日益完善,以数据仓库、数据挖掘等技术为基础的水文数据挖掘体系将逐步走向实用化.

As the characteristics of hydrological data of river basin is of massive, complex, temporal and special, we have established hydrological data-mining system of river basin which consists of data layer, organizational layer, mining layer and decision-making layer on flood management and water supply, and constructed the analytical flow of this system from the viewpoint of data warehouse, data-mining and metadata management.The system proposed in this paper is applied to hydrological forecast and operation.With sufficient data, the system is much useful for formulating feasible hydrological forecast and operation scheme.With the development of data management and analysis technology, hydrological data-mining system of river basin based on data warehouse and data-mining technology will be applied gradually.
