长江水文泥沙信息分析管理系统研究

阐述了长江水文泥沙信息分析管理系统的总体结构、设计理念和系统功能以及系统应用情况,重点介绍了矢量数据编辑子系统、对象关系数据库管理子系统、水文泥沙专业计算子系统、水沙信息可视化分析子系统、长江河道演变分析子系统、基本信息查询子系统、长江三维可视化子系统、水文泥沙河道信息网络发布子系统等8个子系统的功能实现.该系统采用数据库、GIS、遥感、网络融合技术,实现了对长江流域近110亿条水文泥沙监测数据和5万余幅地形观测资料的统一管理,提高了长江水文信息处理技术水平.

Research on Information Analysis and Management System on Hydrology and Sediment of the Yangtze river

This paper presents the overall structure,design idea and systematic function and application condition of information analysis and management system on hydrology and sediment of the Yangtze river and mainly introduces function realization of 8 sub-systems of editing sub-system of vector data,management discipline of object relation database,computation sub-system of hydrology and sediment sub-system,visualized analysis sub-system of water and sediment information,analysis sub-system of the Yangtze river channel evolution,inquiry sub-system of fundamental information,3 dimensional visualized sub-system of the Yangtze river,network publication sub-system of hydrology,sediment and river channel information.The system makes use of technologies of database,GIS,remote sensing,network integration and realized integrated management of 11 billion hydrologic and sediment data and 50 thousand topographic maps,improved hydrologic information treatment level of the Yangtze river.
