In order to make a good effect on river management and ensure the safety of water used in people's production and everyday life, a perfect river water management system should be built necessarily. Computer technology is widely used in water environment management. Developing visual simulation system of river environment is one of the important works to push river water management scientifically. In this paper, based on CIS, as a visual reality simulation tool, Vega was applied to develop visual simulation system of river environment. With the system, the geography information of inspecting stations and water quality information of the river can be shown on CIS, further more, the virtual reality roam function was realized, giving a basic support on software to improve the level of river environment management.%为了对河流进行有效管理,保障人民生产生活用水安全,必须建立完善的河流水环境管理系统.计算机技术已广泛用于水环境管理.开发河流水环境可视化仿真系统是推进河流水环境管理科学化的主要工作之一.基于GIS平台,结合Ve-ga虚拟现实仿真工具开发河流水环境可视化系统,不仅能够将各监测站点地理信息、河流水质信息等在GIS上展示,还实现了河流虚拟现实漫游的功能,为提升河流水环境管理水平提供基本的软件保障.
