| 摘 要： | 以15块经营密度试样地资料为基础，用转移概率矩阵方法建立马尾松人工林直径分布动脉转移模型。模型在间伐试验林的高、中、低密度林分中的应用结果表明，林分总断面积的预测精度依次为97％，98％，98％。同时表明，比例法的应用精度普遍高于公式法。

| Abstract: | On the basis of 15 samples for the experiment of intermediated felling,the dynamic transfer model of diameter distribution in masson pine plantations was established with the method of transfer probability matrix.The transfer probability was computed with the diameter growing model of individual tree,in which the formula method and proportion method were computed.The dynamic transfer model was used in stands with high,middle and low desity.The reuslts made clear that the forecast precisions of stand basal area were 97%,98%,98%,respectively at the same time,it made known that the calculating precision of the proportion method was higher than that of the formula method generally. |
