Abstract:
The study on the tree growth for four species groups of commercial timber in Koh Kong province, Cambodia’s tropical rainforest is described. The simulation for these four groups had been
successfully developed in the 5-year interval through year-60. Data
were obtained from twenty permanent sample plots in the duration of
thirteen years. The aim for this study was to develop stand table
simulation system of tree growth by the species group. There were
five steps involved in the development of the tree growth simulation:
aggregate the tree species into meaningful groups by using cluster
analysis; allocate the trees in the diameter classes by the species
group; observe the diameter movement of the species group. The
diameter growth rate, mortality rate and recruitment rate were
calculated by using some mathematical formula. Simulation equation
had been created by combining those parameters. Result showed the
dissimilarity of the diameter growth among species groups.
