抄録・要旨

There are many studies on Ate plantations in Noto region. While the plantations are managed with selective cutting in Noto, we have an even-aged uniform plantation of Ate in Matswe Experimental Forest, Shimane University. We describe here the stand structure of Ate plantation.
Mean diameter at breast height was 7.9cm. Mean height was 4.73m. Basal area was 10.9m^2/ha. Frequency distribution of diameter at breast height，height，and basal area was not normally distributed and spread wider in right side of the mean.
Height (H)-diameter at breast height (D) curve was calculated as following，

1 / H = 0.5982 / D ＋ 0.1439 (for the trees with less than 9 cm in D)
1 / H = 1.058 / D ＋ 0.06669 (for the trees with 9 cm or more in D)

According to the result, this stand is expected to grow at an accelerated
rate in the near future.
