摘要
本文论述了削度方程的类型及其在研制材种出材率表中的重要意义，结合全林分生长模型，林分自然稀疏模型以及林分结构模型编制了日本落叶松林分材种出材率表。经检验精度符合要求。从而为及时准确地掌握林分的材种结构及变化，进行林分材种结构调整，落实限额采伐森林面积提供了重要的理论依据。
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.
