The framework design,structure,function and running mechanism of forest ecological and resources information sharing system was given in this paper. Three core techniques of the sharing system,including the principles,model and design of the WebGIS subsystem,multi-dimension spatial data organizing,and presentation and spatial analysis online,were discussed in detail. Finally,the application and related problems of the sharing system was put forward.
