| Abstract: | This article, using the principle and method of system dynamics, analyses the causality of forest harvesting system and gives its causality and flow chart diagram .Then, the mathematical model of forest harvesting operation system was developed with differential equations and simulated with computer. Being as an example of forest harvesting system in Baishishan Forest Industry Bureau , the future trend of main parameters(harvesting equipment, stand volume,annual logging quantity) in the system are predicted. |
