The Stand Visualization System (SVS) is a good software tool in forest inventory plot and subcompartment visualization. Its direct and tridimensional images provide a new method for the study of stand increment and forest visualization. In this paper, the stand conveying was done in plantation of 16-year-old slash pine and the increment data of trees were collected. The visualization process of slash pine plantation stand was further done and its operation and notes of the Stand Visualization System were introduced in detail. The simulating outcomes were analyzed and discussed. These provide a reference for the construction and development of forest visualization and digital forestry in China.
