Abstract:

This paper described the problem of growth and yield model anciently and the meaning of mixed effects models in forest growth model. The expressive forms and arithmetic of linear mixed effects models and nonlinear mixed effects models was introduced separately. The study's evolve of mixed effects models about the height, the basal area and tree volume is reviewed in detail. The problem and research foreground of the future was pointed out.

Key words: mixed effects models, height, basal area, tree volume
