<正>本文提出了一致性分段式削度方程和一致性材积比方程。为了评价这两个方程,利用杉木材料分别与其它已有削度方程和材积比方程作了比较,结果表明这两个方程的效果较好。另外对所比较的削度方程和材积比方程作了评价。

In this paper a compatible segmented taper equation and a compatible volume ratio equation are developed. In order to evaluate these two equations, they ase compared respectively with other taper equations and volume ratio equations in use, using data of Chinese fir (Cunninghamia lanceolata Hook) stands. Results show better effectiveness of these two equations than others. Evaluations are also made on taper equations and volume ratio equations being compared.
