Tuning method DBH* class Tree density Mortality DBH* class Tuning parameters So that these two distribution can be expresed Establishment rateMortality *DBH: Diameter at Breast Height
DBH class Tree density Mortality DBH class Total biomass Growth rate for each DBH class Size structureCompetition among size class Most fundamental properties of the production and dynamics can be captured by this method
Tuning results Boreal needle-leaved evergreen wood Shiretoko1 (1.25ha, 6yrs) Simulated Shiretoko2 (2.25ha, 6yrs) Observed (0.09ha×20) Mortality (prop. per year) Tree density(N per ha) DBH class (5cm interval)
SimulatedObserved (0.09ha, 300yrs) Mortality (prop. per year) Tree density(N per ha) Tuning results Temperete broad-leaved evergreen wood South Kyushu1 (0.44ha, 5yrs) South Kyushu2 (1ha, 5yrs) DBH class (5cm interval)
