From this research, we obtain the following conclusions:1 There are marked relativity between DBH and height of trees, between DBH and the ratio of height to DBH. The relativities can be described by the model, H=3.0683+0.3936Z) and F=0.713 8-0.006 3D.是什么意思_From this research, we obtain the following conclusions:1 There are marked relativity between DBH and height of trees, between DBH and the ratio of height to DBH.
