Abstract
To characterize the root strength changes of Pinus densiflora by elapsed years after forest fire, we measured and analyzed the tensile force and strength of the roots using the universal testing machine for 4 years. The deterioration rate of the root strength was higher in small diameter class than that in large diameter class. Especially, the deterioration was highest of the root strength at the second year in all surveyed diameter classes and the mean deterioration rate of the root strength was 61% by that time. The tensile strength based on the simulation by ordinary differential equations deteriorated more than 50% in all diameter classes within 2 years after forest fire.
