为改进一元材积模型建模技术,以黄山松(Pinus taiwanensis)为研究对象,构建了基于伯克式的一元材积模型,通过交叉建模和检验同步进行的建模思路,利用逐步回归法求解参数,得到黄山松一元材积方程。并通过模型评价指标对比分析,其拟合效果好于由TOPSIS法得到的最优一元材积方程,弥补了黄山松一元材积表的空白,对科学经营管理黄山松天然林、森林资源清查具有重大意义。
In order to improve the modeling technology of one-dimensional volumetric model, a Burk-type one-dimensional volume model was constructed with Pinus taiwanensis as the research object. Through the cross-modeling and testing of synchronous modeling ideas, the stepwise regression method was used to solve the parameters , Get Huangshan pine one volume equation. Through the comparative analysis of the model evaluation index, the fitting effect is better than that of the optimal univariate volume equation obtained by TOPSIS method, which can make up for the blank of the Huangshan pine monoculture volume table, which is of great significance to the scientific management and management of Huangshan pine natural forest and forest resources inventory .
