摘要
目前延边林业生产中仍在使用１９７５年编制的《吉林省立木材积表》中的东部次生林区针叶树一元立木材积表。我们利用３３８株样木资料，采用树高曲线法检验了上述材积表对延边赤松的适用性，结果表明存在较大误差，为此用平均实验形数法拟合出新的材和方程：Ｖ＝０．９×１０－１－１５０６６．１×１０－６（Ｄ＋１１．５）＋５９５８．８×１０－７（Ｄ＋１１．５）２，编制了天然赤松一元立木材积表。
Now single-entry volume table of needle-leaved forest in the east secondary stand region,which is from Tree Volume Table of Jilin Province,compiled in 1975,is still used.Calculating 338 sample srees and using height curve,the suitability of the aforementioned volume table for Japanese red pine was tested in this paper.The result showed there was a great error. For this reason, natural Japanese red pine stand single-entry volume table was compiled by using the new volume equation: V = 0.9×10-1-15066.1×10-6(D+11.5) +5958.8 ×10-6 (D+ 11.5), which was formed by using the average experimental form factor method. The average life span of the example trees is 40 years.
