摘要: 以福建省永安市尾叶桉一元材积表和一元材种出材率表为例,运用相关分析与曲线回归分析方法定量研究两数表中各径阶材积和总出材率之间的关系。研究结果表明:各径阶材积与出材率呈明显正相关关系,回归方程为y=e4.429-0.004/v,相关指数为0.997;永安市尾叶桉随着材积的增大,其出材率趋于84%。明确各径阶材积与出材率之间的关系,既可简化编表工作的人力、物力,为其他数表关系的研究提供参考,也可为完善林业数表体系提供依据。

Abstract: A study was conducted on the relation between single entry volume table and single entry outrun table for Urophylla of Yong'an City,Fujian Province.This article researched the relationship of each diameter class volume and total wood volume ratio in the two tables,using curve correlation analysis and regression analysis methods.The results showed that each diameter class volume and wood ratio have significant positive correlation,regression equation is y=e4.429-0.004/v and the correlation coefficience is 0.999; As Urophylla volume increases,the wood ratio tends to be 84%.Ascertaining the relationship between volume table and wood table would simplify the compilation work,decrease the labor and material resources,but also provide reference for study on other tables in relationship and improve the forestry table system.

Key words: Urophylla single entry volume table, single entry outrun table, correlation, curve regression
