| 摘 要： | 精确测定立木材积始终是困扰森林计测的难点,文章选用来自山西部分林局的油松天然林解析木实测资料,运用数理统计方法．对日本鸟取大学井上昭夫与黑川泰亨推导出的计算针叶树立木材积的理论材积式V=1/[2(1—H_b/ H)]~(1．060)×π/4D_b~2×H,进行了适用性和应用精度检验,并同该地区经验材积式进行了对比分析,结果表明,该理论材积式在华北地区的适用性还需进一步的检验分析,原来的地方材积表(式)仍有适用价值。

| Abstract: | How to precisely measure tree volume is one big challenge which puzzle the forestry managing.This article dis- cussed a theoretical volume equation's applicability of coniferous species.Deduced by Inoue and Kurokawa,from Japanese Niaoqu University.Its expression isV=1/[2(1-H_b/H)]~(1.060)×4D_b~2×H.The author selected 130 sample trees data a- bout natural pinus from part regions of Shanxi forestry bureau.The statistics methods was used to analysis its applicability and precision.At the same time,this zone's empirical volume equation was tested too.The results showed that the applicabil- ity of the theoretical volume equation should be tested farther.The empirical volume equation's can still fit to measure the tree volume. |
