Growth and management interactive visualization simulation method for forest stand

The invention relates to a growth and management interactive visualization simulation method for a forest stand. The growth and management interactive visualization simulation method for the forest stand comprises the steps that firstly, variables needed by a full forest stand growth model, a diameter class growth model, an individual tree growth model and a forest measurement factor estimation model are established; secondly, a user-defined forest stand growth model analyzer is constructed; thirdly, the current situation and the variables of the forest stand after growth changes are automatically stored dynamically, extracted and calculated; fourthly, an individual tree visualization model parameter calculation method based on a user-defined forest stand growth model is constructed, and interactive forest stand growth visualization simulation under the user-defined forest stand growth model is achieved; fifthly, visualization simulation is carried out on the forest stand structures, forest stand two-dimensional states and three-dimensional scenes before and after management of the forest stand by adopting the GDI and drawing technology and the MOGRE technology, and growth and management interactive visualization simulation of the forest stand is achieved.
