Abstract:With the Chinese fir,Cunninghamia lanceolata,plantation in Huangfengqiao Forest Farm of Hunan Province, as the research object, and from the viewpoint of forest thinning, the principles and methods of forest management visualization were studied and a forest management-oriented virtual forest prototype was developed. The system used forest inventory data as data source and achieved the functions of virtual forest roaming, information query of subcompartment and forest stand thinning simulation, etc. so it was possible to offer a new platform for forest resource management and its visualization.
