通过对62块典型样地进行调查，采用相对直径株数累积百分数、正态分布函数、Weibull分布函数、Logistic生长函数等对不同密度和不同年龄的秃杉人工林分进行了直径结构分析和函数拟合，并进行了统计检验。研究结果表明：随林分密度减小，直径株数累积百分数曲线规律性右移；在任意的相同株数累积百分数所对应的不同密度的直径，密度越大，直径越小；Logistic生长函数对于腾冲秃杉人工林直径分布的拟合效果优于Weibull分布函数和正态分布函数，可用于该研究区秃杉人工林林分直径分布及生长量预测。

Through the investigation of 62 typical samples ,the article adopts the cumulative percentage of relative diameter strains ,normal distribution function ,Weibull distribution function and Logistic grow th function to conduct the diameter structure analysis and function fitting of artificial forest of Taiwania flousiana with different density and age .In addition ,a statistical test is also conducted .The results show that with the decrease of stand density ,the curve of cumulative percentage of relative diameter strains moves right regularly ;in any of the same cumulative percentage of relative diameter strains which corresponds to the diameter with different density ,the greater the density is ,the smaller the diameter will be;The imitative effect of Logistic growth function to diameter distribution of artificial forest is better than that of Weibull distribution function and normal distribution function ,which can be used in the prediction of the stand diameter distribution of artificial forest and the increment of the Taiwania flousiana in the study area .
