中文摘要：

为提高水库的现代化管理水平，以江西省境内大中型水库为研究对象，综合运用空间信息技术、3D WebGIS、Internet、空间数据库以及三维虚拟仿真等高新技术，建立了江西省典型水库信息管理系统。系统具有水利工程三维场景虚拟、水库水情监测、洪水预报及调度、洪水淹没与评估及地质资料查询等功能。研究成果已在新建县幸福水库成功应用，可为水库主管部门提供科学数据与决策支持。

英文摘要：

In order to improve the modernization management level, with regard to the research for medium and large reservoirs in Jiangxi Province, an information management system for these typical reservoirs is developed by spatial information, 3D Web GIS, Internet, spatial database, 3D virtual simulation technology and so on. The system has the functions of 3D WebGIS simula-tion, flood forecasting and dispatching, flood submergence and flood damage assessment, geological data inquiry, etc. The sys-tem has been successfully applied in the management of Xingfu Reservoir in Xinjian County and provided scientific data and deci-sion support for reservoir management departments.
