Based on the analysis of the contents and technical characteristics of different scale forest visualizationmodeling, the design of individual tree modeling, law of stand structure, forest scenery rendering etc. were studied.On the basis of study of related theories and algorithms, a large-scale virtual forest environment p rototype system wasdeveloped. The system used hybrid rendering as a main technology for modeling and rendering of the forest. Thescene was built to rep resent the data structure of the models by octree subdivision, and to imp lement the followingfunctions: large-scale virtual forest simulating and information query of subcompartment. The experiment showedthat it could offer a virtual environment for forest resource management.
