Wang Xiaoming;Key State Owned Forest Administration Of Inner Mongolia,Greater Khingan Rang;
Xingan Larch( hereinafter referred to as the larch and birch) is the main tree species in Daxing'an Mountain forest area. The volume accounted for more than 80% and the bark is an important raw material for industrial tannin. In addition the birch bark can also be used as medicine,extraction of birch bark oil,the production of handicrafts. Therefore,studying on the bark thickness( hereinafter referred to as Pihou) and DBH relationship establish the mathematical model,it can provide the basis for the prediction of bark yield.
