Abstract: Considering the constraints of many factors such as high difficulty, high risk, high cost, irreversibility and ecological damage of timber production in logging area, the virtual simulation experiment system of forest operation technology and equipment is developed with the integration of Web graphics library (WebGL) technology, network technology and 3D simulation technology. The virtual simulation experiment including cutting area creation and main cutting analysis, logging operation technology and equipment, skidding operation technology and equipment is designed. Through the parameter variable control, operation process observation and key technology practice, students carry out skill training according to the operation procedures. The virtual simulation experiment system has good practicality, interactivity and teaching effect, which is helpful to improve students’ practical ability and innovative thinking ability. It can provide reference for experimental teaching of forest engineering and related majors.
