The change of the stand structure and the volume increment of conifer mixed forest managed by selection system were investgated at KITSUNEGAJO sample plot set up in Numata Cho, Hiroshima City in 1971.
The change of processes of diameter distribution in each cutting cycles were shown in Table 1, and mean diameter distribution were represented by twisted J-shape distribution (pearson's I type). The regeneration by natural seedings of forest succeeded during this wark. The current annual volume increment in each cutting cycles ammounted to 17.7m^3 and 14.9m^3(mean 16.3m^3) per ha., respectively. The remaining trees over 20cm D.b.h. produced the major part of the total increment. |
