摘要
以不同分布区域的思茅松标准木为基础数据,对思茅松活立木材积进行分析处理,运用多元线性回归方法,建立思茅松活立木材积与胸径、树高的回归方程为V=0.00023004×D^(2.07775740)×H^(0.31626704),经F检验回归关系显著,预测结果误差较小。
Living tree volume were analyzed on the basis of data concerning standard wood of Pinus kesiya var. langbianensis. The regression equation of volume and DBH as well as tree height of the living wood were established. Equation of regression is V：0. 00023004 × D2.07775740 × H0. 31626704 , which shows regression relationship significantly with F-measure test.
