| 摘 要： | 以正形数为基础,提出V=f0 1h·g0 1h·h的单株立木材积估测式,经6个树种944株样木试验,并与二元立木材积表法进行了比较,结果表明这个立木材积式取得了良好的估计效果,可以在立木材积估测中应用。 |

| Abstract: | In this paper the estimating equation V=f(0.1h)·g(0.1h)·h of single tree's volume is put forward on the basis of studying normal form factor. In the experiment 944 sample trees of six tree species were used in order to verify the equation.It was also compared with two-enter volume tables.The results show that the estimating equation of standing volume is effective and therefore can be put into practical use. |
| Keywords: | standing volume estimate normal form factor |
