林分直径结构的Weibull研究

Study on Stand Diameter Structure of Weibull Taking Larix kaempferi(Lamb.) as an Example

摘要:

摘要：日本落叶松直径服从Weibull分布，本研究编制了直径分布预估概率表；其形状参数C取不同的值时，其分布曲线形状类型即不同,当1.8＜C＜3.1时,分布图形为正偏,中小径阶的林分为多数。

Abstract:

Abstracts:The diameter of Larix kaempferi(Lamb.) obeyed weibull distribution, and diameter distribution prediction probability table was compiled in this study. The distribution curve shape type differed with the value of shape parameter C. When C was greater than 1.8 and less than 3.1, the distribution pattern was positive skew distribution, and stand diameter with small and medium class accounted for the majority.
