单木生长模型与林分生长模型耦合的方法--以油松为例
The Coupling Method for Individual Tree Growth Models and Stand Growth Models:A Case Study of Pinus tabulaeformis
摘要
Abstract
Relative diameter was used as the individual tree competition index, through introducing the dummy variables to integrate thinned stands and unthinned stands,the models of individual tree basal area and volume growth were established.The inspection showed that the prediction accuracies of the models for thinned stands and unthinned stands of Pinus tabulaeformis were over 96%. The stand growth models were derived from the individual tree growth models by transformtion, the inspection showed that the prediction accuracies for stand basal area and volume of Pinus tabulaeformis were over 86%. The method of deriving stand-level growth models from individual tree-level growth models has solved the problem that prediction effects of different level models on the prediction of the same stand factor was not consistent,so the individual tree-level and stand-level growth models have been coupled together organically as a whole.This method applies not only to the pre⁃diction of stand basal area and volume,but also applies to the prediction of other stand factors.关键词
