摘要: 在福建省茫荡山自然保护区天然小叶青冈(Cyclobalanopsis myrsinaefolia (Bl.)Oerst)林设置标准地,选取小叶青冈平均木做树干解析,利用理查兹方程、逻辑斯蒂方程、对数方程、Korf方程以及二次曲线方程等方程模拟胸径、树高、材积与年龄的相关关系,并进行分析对比。结果表明:理查兹方程模拟效果最好,小叶青冈胸径与树高连年生长量达到最大值的年龄分别为25 a和22 a,而材积连年生长量在15 a时达到最大,平均生长量在25 a达到最大。

Abstract: Sample plots were set up in Cyclobalanopsis myrsinaefolia forest in Mangdang Mountains Nature Reserve of Fujian Province.Mean trees were selected in the sample plots for stem analysis to fit growth equation.The result showed that the Richards equation was the optimal growth equation,the current annual increment of DBH and height arrived at maximum at the age of 25 and 22 years respectively,while the current annual increment of timber volume arrived at the maximum at the age of 15 years,and mean annual increment arrived at the maximum at the age of 25 years.

Key words: Cyclobalanopsis myrsinaefolia(Bl.)Oerst, growth equation, height, diameter at breast height(DBH), volume
