| 摘 要： | 本文以佳木斯市横头山林场樟子松人工林作为研究对象,研究樟子松人工林林木的胸径生长规律,分别用修正指数方程、理查德方程、逻辑斯蒂方程对各等级大小胸径生长数据进行拟合。结果表明,用理查德方程拟合胸径生长较好;胸径连年生长量达到最大的时间在11-14年之间,当时的胸径则差异较大,优势木和劣势木相差将近2cm,范围在5.5-7.5cm之间,年生长最大值的差异较明显,在0.56-0.87cm之间。

| Abstract: | Using the data of Mongolian pine plantation of Hengtou forest farm in Jiamusi city,the diameter growth regulation for Mongolian pine was studied in this paper.The modified index model、Richard growth model、Logistic model were used to fit the diameter growth data for the trees with different size.The result shows that Richard growth model is better for diameter growth;the time when the annual value of diameter at breast height reached top is between 11 to 14 years,at that time diameter at breast height is different clearly.The difference between dominant tree and dominated tree is 2cm,and it range from 5.5cm to 7.5cm.Diameter annual growth can range from 0.56cm to 0.87cm.. |
