DYNAMIC OPTIMIZATION OF UNEVEN-AGED FOREST HARVESTING REGULATIONS AND ITS COMPUTER SIMULATION

Based on the matrix model of the growth of uneven-aged forest stand, the problem of the dynamic optimization of uneven-aged forest harvesting regulations is studied and a computer model associated is established for its simulation in this paper. The shortest and greatest-in-benefit cutting path for finding the ideal state from the current one of uneven-aged forest state can be determined in the computer model by means of a method extending regulation period. An associated software is then developed in the medium-size computer FACOM M-340S. In solving the problem of the dynamic optimization of uneven-aged forest harvesting regulations, the obvious advantage of the approach given here is centred on the determination of the feasible region and the shortest regulation time. The approach and software are considerably worth to the forest-managers in the harvesting decision-making and forecasting.
