中文摘要	With the development of "digital valley" and "virtual reality", valley simulation system can be extensively used in integrated management of river as an innovative approach and technology. The implementation method of large area valley simulation system based on Creator/CTS/VegaPrime was explored. Jingjiang valley simulation system was developed based on MFC in VC++ platform through DEM data of 30 meter grid spacing and ETM+ images of 15M spatial resolution and 1M areal photograph. Hydraulic model management and attribute information query functions were realized in the system. The technology details of virtual texture, multi level of detail, tiled terrain dynamically paging management were expounded, which solved the problems of high spatial resolution texture and large area terrain real roaming in valley simulation management system.
