Parameters of Height-Age Models for Larix kaempferi Provenances
Larix kaempferi in provenance test forest in Dalaoling Forest Farm of Yichang County were chosen as experimental materials.Dummy variable model was used to test difference in parameters of height growth of seven L.kaempferi provenances during stand age 3-10 and 24.Flexible Richards equation and logarithmic linear Schumacher were chosen as basic model.From Suchmacher model,there was more significant difference in asymptote parameter than slope parameter for seven L.kaempferi provenances.From Richards model,there was more significant difference in asymptote parameter than growthrate parameter and shape parameter.With difference between parameters of L.kaempferi provenances,we should chose different equations to describe height-age models.
