吉林省主要林分类型蓄积增长率的研究

Study on the Growth Rate of Main Forest Types in Jilin Province

针对采用林木生长率表调整森林资源档案偏高的现实,本文以连续清查固定样地资料为数据源,利用理查德(Richands)生长曲线模型试编了吉林省主要林分类型蓄积增长率表,通过应用表明所选生长函数的形式基本符合林分的生长规律,文章还探讨了利用林木生长率与利用林分增长率调整森林资源档案的差异性。

In view of the fact that the forest resource growth rate table is used to adjust the high forest resource file, this paper uses the continuous check of the fixed plot data as the data source, and uses the Richands growth curve model to compile the growth rate of the main forest type of Jilin Province. Through the application, the form of the selected growth function is basically consistent with the growth law of the forest. The article also discusses the difference between the forest growth rate and the forest growth rate.
