| Abstract: | In this paper, the authors discusse the various types or taper equations and their significance in developing merchantable volume tables and established the stand outturn tables of wood sorts for Japanese Larch, in combination the stand growth models, the models of distribution of stand structure and the stand natural thinning models. By testing, the precision met the requirement satislactorily, an important foundation was given in theory for accurately grasping the stand structure of wood sorts and its change in time,adjusting the structure and setting a limit to the area of forest felling. |
