数字流域研究平台建设雏议

本文建议数字流域研究平台的建设，应是在三维虚拟仿真场景的支撑下，以原型观测的历史数据和实时信息为基础，以实体模型试验为纽带，以数学模型计算为工具，复演流域的历史进程，研究流域的现状，预报流域的未来发展。文中重点对综合研究方法的协调进程和虚拟仿真系统开发的关键技术进行了论述，对相应的解决方案提出了建议，以都江堰为例探讨了系统的应用前景。

On the construction of research platform of digital valley

The scheme of research platform construction of digital valley is proposed. On this platform the 3-D virtual simulation, the field data and real time information of prototype observation and the experimental data of physical model as well as the computational result of mathematical model are organically integrated. It can be applied to demonstrate the historical evolution, study the present status and forecast the future of the valley. The coordination of the comprehensive research approaches and the key technology for development of virtual simulation are discussed and the corresponding programs for solving these problems are suggested. The application of the proposed platform to Dujiangyan Hydro Project is given to demonstrate the feasibility and application prospect of the platform.
