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
