Abstract: A dynamic model is built up by means of system dynamics method for the development offorest resources in Liaoning province.Prediction and strategy research are made for the fo-rest ecology and timber production in 2000 in Liaoning.The impactions of various designson the development of forest resources are understood by adjusting different parameters andadding disturbances to the model.Various parameters are determined according to the dataprovided by Land Dept.and Forestry Dept.of Liaoning province,the data of provincialforest statistics in 1978 is taken as the original values for running model,which is perfor-med on IBM PC/X7 computer in DYNAMO language of system dynamics.
