Abstract. The relationship between height and diameter (H-D) is an important component
in forest growth and yield models, and a better understanding of the
relationship will improve forest monitoring, management, and biomass
estimation. Sixteen nonlinear growth functions were fitted to H-D data for
1261 trees from a Cryptomeria fortunei plantation in the Pingba
region of Guizhou Province, China. Of the 1261 trees, 80 % were randomly
selected for model calibration, while the remaining trees were reserved for
model validation. All models were evaluated and compared by means of
multiple-model performance criteria. Although all 16 models showed a good fit
to the dataset and each of them accounted for more than 75 % of the total
variation in height, a large difference in asymptotic estimates was observed.
The Chapman–Richards, Weibull, and Naslund models were recommended for
C. fortunei plantations, due to their satisfactory height prediction
and biological interpretability.
