| 摘 要： | 为了进一步探索树高与胸径的相关关系,本研究以黑龙江省帽儿山林场为样地,选取林区中杨树（Polar）、白桦（Birch）、紫椴（Tilia）、枫桦（Betula costata）、水曲柳（Fraxinus mandshurica）林等5种主要树种为研究对象,通过SPSS17.0对胸径（D）和树高（H）的数据进行处理,应用7个常见树高-胸径模型来模拟相关关系,通过决定系数R2评价出了每个树种树高-胸径最优模型形式,所有树种最优模型的相关系数都达到了0.9以上,模型拟合的精度高.结论表明：①杨树的树高-胸径最优模型形式为幂函数曲线模型,方程式为：H=4.383D0.418;②白桦树、紫椴树、枫桦树的树高-胸径最优模型形式为三次曲线模型,方程式分别为：白桦树：H=4.785 ＋0.721D-0.008D2-0.00005D3;紫椴树：H =3.985＋0.787D-0.013D2-0.00009D3;枫桦树：H=6.345＋0.769D-0.010D2-0.000047D3;③水曲柳的树高-胸径最优模型形式为幂函数曲线模型,方程式为：H=e1.992＋0.043D.

| Abstract: | To further analyze the relationship between height and diameter at breast height, the sample plots in Maoershan forest farm in Heilongjiang Province were investigated and five main species including poplar, betula platyphylla, tilia amurensis, betula eostata and fraxinus mandshurica were analyzed. The software of SPSS17.0 was used to process the data of diameter at breast height and height, and seven common Height-Diameter regression models were evaluated. The optimal model for each species was selected based on the corresponding coefficient of determination R2. The correlation coefficients of all the optimal models were more than 0. 9, which indi- cated that these models had higher precision. The results indicated ： （ 1 ） the optimal Height-Diameter model for poplar is power function curve model and equation is： H = 4. 383D0.418. （2） the optimal Height-Diameter models for betula platyphylla, tilia amurensis, and bet- ula eostata Trautv are cubic curve model. The equations are： betula platyphylla H = 4. 785 ＋ 0. 721D - 0. 008D2 - 0. 0000503, tilia amurensis H=3. 985 ＋0. 787D -0. 013D2 -0. 00009D3 , betula costata Trautv H =6. 345 ＋0. 769D -0. 010D2 -0. 000047D3. （3）the optimal Height-Diameter model for Fraxinus tuna dshurica Rupr is power function curve-model. The equation is H = e1992＋0.043D |
