| 摘 要： | 树高曲线在林业生产中和林业实践中广泛应用。本文使用红松、华北落叶松和日本落叶松样本373组、499组和414组作为基础数据,分别选用10个树高曲线模型,计算各个模型的参数,并用R2、MD和RMSE对模型精度进行检验,结果表明模型(10)—唐守正方程能较好的模拟树高与胸径的关系,故选取其作为辽宁省东部山区主要针叶树种最优树高曲线。

| Abstract: | The height-diameter model is widely uesed in forestry production and forestry practice.In this study 373,499and 414individual trees of Pinus koraiensis,Larix principis-rupprechtii and Larix kaempferi were used to test ten selected height-diameter models.After calculating of each model,correlation coefficient（R2）,mean deviation（MD）and root mean square error（RMSE）were used to compare among different species and varied models.It is concluded that the Tang’s model the best to calibrate the relationship of height and diameter.So it is selected as the optimal height-diameter model for dominant coniferous species in eastern areas,Liaoning Province. |
