| 摘 要： | 利用吉林省汪清林业局金沟岭林场的963株解析木资料,对由日本井上昭夫与黑川泰亨利用孔兹干曲线推导的针叶树立木材积的理论二元材积公式与东北针叶树二元材积表进行精度检验。结果表明,理论材积式与实际材积和经验材积式之间均极显著相关;理论材积式在红松（Pinus Roraiensis）、落叶松（Larix gmelinii）与云杉（Picea asperatu）的精度验证中均比经验材积式的精度高,而且达到我国材积式适用精度要求,适用于长白山地区针叶树材积的计算。

| Abstract: | 900 analytic trees data of Jingouling Forestry Centre from Wangqing Forestry Bureau in Jilin Province were selected to examine the tree volume precision measured by the theoretical binary volume equation of conifers and the empirical volume equation of Northeast conifers.The results indicate that the theoretical volume is significantly related with the actual volume and empirical volume.And the theoretical volume equation has a higher precision of prediction compared to the empirical volume equation in Pinu... |
