The estimation of growth percentage in volume is an important problem in a forest management.
Growth percentage in height affects tree volume percentage to a considerable degree(0.67-3.75%), and we must pay principal attention to the estimation of the growth in height. In this paper, we compared with 4 methods - PRESSLER'S, SCHNIDER'S, HIRATA'S and (2P_d + P_h) formula - in the accuracy of measurement at the stand of Kromatsu(Pinus Thunbergii Parl.) The results of the experiments and summarized in Tables 1-3 and illustrated in Figures 1-3. |
