摘要
通过在腾冲县中和乡设置10块秃杉人工林标准地,在标准地每木检尺调查的基础上,采用Weibull分布函数、Logistic方程、Gompertz方程对秃杉人工林林分的直径分布进行拟合,并进行χ2检验。结果表明,Logistic描述秃杉人工林直径分布效果最好,可用于秃杉人工林的直径分布和生长预测,为合理经营秃杉人工林提供了科学的理论依据,对秃杉人工林的定向培育具有一定的指导意义。
We choosed 10 normal grounds and measured each tree, then used relative Weibu]l distribution, Logistic distribu- tion and Gompertz distribution to analyse the diameter structure of Taiwania flousiana Gaussen and the Chi square statistics test is applied for the four types of distribution. The result shows that Logistic distribution can do the best to describe the di- ameter structure of Taiwaniaflousiana forest. So that a scientific theory for managing Taiwaniaflousiana Ganssen properly is provided.
