江西瑞金毛竹林林分直径分布研究
|
摘要
在江西瑞金林区毛竹林典型样地立竹胸径实测调查的基础上,利用正态分布、Γ分布和Weibull分布密度函数对林分直径分布进行拟合,并进行了χ~2拟合优度检验。结果表明:试验区毛竹林林分直径分布分散程度较大,毛竹林林分直径分布符合正态分布,近似符合Γ分布和Weibull分布。这为研究毛竹林林分结构特征及该区域毛竹林的合理经营提供了科学的理论依据。
Based on the field measurements of diameter at breast height(DBH) at Phyllostachys edulis typical sample plots in Ruijin City,Jiangxi Province,stand diameter distribution were fitted with normal distribution density function,gamma distribution density function and Weibull distribution density function respectively.Finally,Chi-square goodness of fit tests were performed on simulated data to compare the fit of the models.The results showed that the stand diameter distribution had greatly dispersion degree at Ph.edulis forests in experimental area.Stand diameter distribution of Ph.edulis forests were accord with normal distribution,and it were obey approximately gamma distribution and Weibull distribution.These would be certain scientific theoretical foundation for stand diameter distribution research and rational management of Ph.edulis forest in experimental area.
