Abstract: The Control Method, as an intensive management method used in uneven -aged forest, was firstly experimented in China. A method of the integration of one modified parameter prediction model (MPPM) and one linear programming method was proposed to be used for predicting and simulating standing stock growths and selective cuttings of uneven-aged stands. Because diameter distributions of stands were fitted by Weibull distribution, the MPPM was much suited to growth predictions of uneven-aged stands. Results of predictions and simulations to the experimental uneven-ages stands locoted at Wangqing Forest Enterprise of Jilin Province showed that not only stable timber harvests but also sustained standing stock growths could be gotten with 5 year selective cutting cycle and suitable selective cutting intensities in longterm selection systems. By selective cutting simulations to the five experimental stands, suitable selective:cutting intensities of them were determined and recommended.
