摘要
通过设置4种不同的造林密度试验来研究密度对桉树无性系林分生长的影响,并以Richards生长函数为模型拟合了不同造林密度条件下桉树无性系林分生长模拟预测模型。结果表明,桉树无性系林分的生长规律呈现“s”型曲线,用Richards模型拟合其胸径、树高、材积及蓄积量的生长精度很高,相关指数均在0. 996以上,利用所建生长模型可以对桉树无性系林分的生长动态进行预测,为桉树人工林的合理经营提供科学依据。
This paper deals with the effects of 4 different planting densities on the growth of Eucalyptus clone stands and a growth prediction model was established based on Richards function. The growth of the Eucalyptus clone stands presented an “s-shaped” curve, and high accuracy was exhibited by the growth prediction model when its was used to fit the breast height diameter, plant height, volume and growing stock of the trees, the correlation co-efficient being 0.996.
