Measurement of the properties of standing trees with ultrasonics and mapping of the properties


, : Measurement of the properties of standing trees with ultrasonics and mapping of the properties. Bulletin of the Tokyo University Forests ( 96): 125-135

The MOE (modulus of elasticity) of standing trees was measured with ultrasonics. The species used for the experiment were todo fir (Abies sachalinensis) and larch (Larix leptolepis). There were differences between the values of MOE for certain forest stands at different locations within the Tokyo University Forest and for stands of different ages. The velocity of the ultrasonic waves could be used instead of the MOE as an index for the properties of standing trees.
