Abstract: The objective of this work was to establish the models for predicting branch diameters and lengths in the larchplantations. The traditional nonlinear model, including the trees variable nonlinear model, the nonlinear mixed modelsand the nonlinear mixed model containing the error structure of branch diameter and length were constructed based on thedata of 843 standard branches collected from 95 sample trees, and the prediction accuracies were also evaluated, by theanalyses of the changing rule of... More
