根据福建省森林资源连续清查第五次复查样地调查资料,对750个天然阔叶林样地调查资料进行整理并进行卡方检验、剩余分析及Log-线性模型的拟合,以分析地貌与林分蓄积之间的关系。结果表明:χ^2检验中地貌和林分蓄积的连带关系明显;剩余分析中林分蓄积随着地貌的改变,从而呈现逐渐减少的趋势,这与有序连带测定结果基本一致。但主效应估计分析结果与交互作用效应估计之间有一定的差异,这种差异可能是由天然阔叶林受人为影响而造成的。
According to the fifth continuously check of forest resources of Fujian Province, the data investigated from 750 plots were analyzed. After χ^2 examination, the residual analysis and the log - linear simulating, relationships between stand stock and landform were analyzed. The major results are as follows:the rela- tion between stand stock and landform is obvious in χ^2examination; and the stand stock is changing with the changes of landform, which is consistent with the results of the order association determination. But there are some differences between the estimations of major effect and interaction effect, which might be caused by the influence of human factors on broad -lanwrl woodland.
