摘要: 为深入探究林木的生长规律、更好地保护珍稀树种,对七姊妹山黄杉群落进行了调查。选用7种常见的回归模型对黄杉的胸径-年龄、树高-年龄、树高-胸径之间关系进行分析。结果显示:黄杉的胸径、树高与树龄成正相关,树高与胸径也成正相关,三次曲线模型可以很好地表达黄杉胸径-年龄和树高-年龄关系,表达式为:y=-0.0001x3+0.011x2+0.179x+4.44及z=0.00007x3-0.015x2+1.105x-10.81;幂函数z=1.778y0.659是描述黄杉树高-胸径关系的最优模型,并对其可靠性进行了检验,结果显示:实测值和预测值无显著差异(P>0.05),表明所选的最优方程可以用来估算黄杉年龄、胸径和树高的值。本文可为该区域黄杉生长规律和预测林木蓄积量研究提供理论支撑。

Abstract: A survey was conducted in Qizimei Mountains Nature Reserve about the Pseudotsuga sinensis communities to further analyze the growth of regular trees and better protect the rare species.Meanwhile,seven common regression models were applied to study the correlation of the DBH and age,tree height and age,tree height and DBH of the Pseudotsuga sinensis.The results showed that there is a positive correlation between DBH and age,tree height and age of the Pseudotsuga sinensis,as well as DBH and tree height.The cubic equations perform the best for describing the relationship between age and DBH,age and height.The equation are:y=-0.0001x3+0.011x2+0.179x+4.44 and z=0.00007x3-0.015x2+1.105x-10.81;Moreover,the best correlation model is z=1.778y0.659 for modeling of tree height and DBH.The optimal models were tested for reliability and the result shows there is no significant difference between predicted and observed values(P>0.05),which demonstrated the best models can be used to estimate the value of age,tree height and DBH of the Pseudotsuga sinensis.Furthermore,the study can further provide theoretical support for the regional research on the growth of the regular Pseudotsuga sinensis and the prediction of the forest volume.
