Visual Simulation Technique of Decision Making of Interactive Stand Management Methods

A technique platform was developed for adapting to forest intensive management by applying a variety of visual simulation techniques. Firstly, thirteen stand management relevant activities were customized and expressed graphically by using the WF. On the basis of the decision making activity of interactive stand management methods proposed in this study, the flow model for visual simulation of decision making of interactive stand management methods was customized by human-computer interaction. Secondly, statistics of stand structure characteristics and the stand state were simulated in 2D by using the GDI+ drawing technique. The stand scene was simulated in 3D by using the MOGRE technique. Finally, a case study of accretion cutting in a Chinese fir plantation was carried out to verify this method. The results showed that this method with operability, flexibility and visibility could be used to create stand management flow models, and that this method could simulate the decision making of methods in order to select a better method from a variety of methods according to the decision making criterion. This method can be applied in stand management practices, can run the better method by considering the specific stand management target, and can significantly improve the stand scientific management ability.
