以塞罕坝地区白桦次生林为研究对象，主要对其直径、树高分布规律进行研究。并运用ForStat统计软件对白桦林分的直径、树高分布进行Weibull分布和正态分布模型拟合，采用χ2检验对其分布拟合效果进行检验。结果表明：塞罕坝地区白桦次生林直径分布总体上呈现正态分布，而树高分布呈现右偏的分布趋势；对其直径分布模拟的研究显示，其直径的Weibull分布函数差异达到显著性。

The article takes the white birch secondary forest in Saihanba as the object of study , and mainly researches the diameter and the tree high distribution rule ,and carries on Weibull distribution and the normal distribution model fitting of the white birch's diameter and the tree high distribution using the ForStat statistics software and χ2 the examination to examine its distribution fitting effect ,finally demonstrating the white birch secondary forest diameter distribution as a whole to present the normal distribution rarely in Saihanba ,but the high distribution presents a cast distribution tendency .The white birch secondary forest diameter distribution simulation research shows a significance in its diameter Weibull distribution function difference ,a better fitting effect in the white birch forest diameter distribution .The tree high distribution of the white birch secondary forest simulation research reveals that there is a significant difference in both Weibull distribution function and normal distribution function of the white birch secondary forest tree high.
