| Abstract: | by using the materials of sample trees, on the basis of multi - equation comparative analysis method, it has been established the related mathematical models for the chest diameter and ground diameter, the tree height and ground diameter. The average relative errors for the established models are less than 2% with the ideal prediction effect. Therefore, it has been provided the scientific base with the application value on practice for the determination of lumbering volume of Slash Pine （Pinus elliotti. ） plantation by using the Binary Tree Volume Table. |
