Huangfengqiao State-owned Forest Farm in Hu'nan Province was selected as a test zone, and a Chinese fir plantation as the research object. The DBH, height, crown width and location were measured. Based on defining the growth models, analyzing forest structure and establishing thinning models with workflow technique, a visualized workflow model which could express the interactive relationship among stand growth, stand structure and stand thinning was built in graphical form by using human-computer interaction mode based on the workflow technique and realized the visual simulation of the interactive thinning. The stand structure, 2-D state and 3-D scene were simulated by using the GDI+ method and the MOGRE technique. The results showed that the interactive relationship among stand growth, stand structure and stand thinning was intuitively simulated and the operability of this method designed for the manager was better, and that the stand structure, 2-D state and 3-D scene were realistically simulated around thinning time. The visual simulation of the interactive thinning can visually simulate the process and effect of thinning and the future state of stand, and can monitor the thinning in real time and promote the computerized management of thinning.

Abstract: Huangfengqiao State-owned Forest Farm in Hu'nan Province was selected as a test zone, and a Chinese fir plantation as the research object. The DBH, height, crown width and location were measured. Based on defining the growth models, analyzing forest structure and establishing thinning models with workflow technique, a visualized workflow model which could express the interactive relationship among stand growth, stand structure and stand thinning was built in graphical form by using human-computer interaction mode based on the workflow technique and realized the visual simulation of the interactive thinning. The stand structure, 2-D state and 3-D scene were simulated by using the GDI+ method and the MOGRE technique. The results showed that the interactive relationship among stand growth, stand structure and stand thinning was intuitively simulated and the operability of this method designed for the manager was better, and that the stand structure, 2-D state and 3-D scene were realistically simulated around thinning time. The visual simulation of the interactive thinning can visually simulate the process and effect of thinning and the future state of stand, and can monitor the thinning in real time and promote the computerized management of thinning.
