三峡水库库尾泥沙数据库管理系统设计与实现

Design and realization of Database Management System for Sediment in Three Gorges Project Reservoir Tail

三峡水库库尾泥沙淤积问题对重庆市的长江航运及取用水等具有重大影响。为了有效掌握三峡水库库尾的泥沙淤积情况,需要对相关水文泥沙数据进行科学合理的管理,为此,开发了三峡水库库尾泥沙冲淤数据库管理系统。介绍了数据库的数据分类及组成情况、数据库设计思想、数据库功能等。系统的成功开发大大提高了三峡水库库尾水文泥沙数据的处理、分析、储存、查询速度,增强了水文数据管理的信息化水平。

The sedimentation in the tail of Three Gorges Project Reservoir has important influence to the navigation and water intake etc. of Chongqing City and it attracts widespread concern. In order to effectively master sedimentation condition in the tail of TGP Reservoir, sediment data should be managed scientifically and reasonably, for this purpose, Database Management System for Sediment in TGP Reservoir Tail was developed. This paper introduces data classification, design idea and functions etc. of the Database Management System. The successful development of the system greatly improved the speed of process, analysis, storage and query of hydrologic and sediment data in TGP Reservoir tail as well as imformatization level of various hydrological data management.
