摘　　要：利用闽北地区鄂西红豆树树干解析材料,再对单分子方程、逻辑斯蒂方程、广义逻辑斯蒂方程、理查兹方程以及Korf方程进行筛选,确定最优的生长建模方程,建立胸径、树高和材积数学模型,对生长曲线进行分析。结果表明,Ⅰ、Ⅱ类地胸径、树高、材积的连年生长量达到峰值分别为25 a、25 a、35 a,平均生长量达到峰值分别为35 a、35 a、50 a;Ⅰ类地鄂西红豆树胸径、树高、材积平均生长量达到顶峰时的时间与Ⅱ类地的并无差别,平均生长量和连年生长量在数值上有所差别。This article uses analytical materials from the trunk of red bean tree in western Hubei in northern Fujian,applies the single-molecule equation,logistic equation,generalized logistic equation,Richards equation and Korf equation to determine the optimal growth modeling equation.Then,the equation can be used to establish mathematical models of diameter at breast height,tree height and volume to analyze the growth curve.Results show that continuous annual growth of diameter at breast height,tree height,and volume of Class I and Class II land reached their peaks of 25 a,25 a,and 35 a,respectively,and the average growth reached their peak values of 35 a,35 a,and 50 a,respectively.The average growth time of DBH,tree height,and volume of red bean trees in Class I land in western Hubei is the same as that of Class II land,and the numerical difference is average growth and annual growth.
