内容記述 Terihaboku (Calophyllum inophyllum L.) forests in Yaeyama Islands (Ishigaki, Taketomi and Kuroshima Islands) were studied for the stand structure. Studied sites were shown in Fig. 1. Frequency histograms of diameter at breast height and tree height were shown in Fig. 2,5,8,12 and 3,6,9,13. Tree height-DBH relations were shown in Fig. 4,7,11,14,15. Main results were summarized in Table 2. Studied sites were four stands, stand age distributed from 32 to 44 years, number of tree per hectare was 2500 to 3900,mean tree height was from 7.1 to 8.3m and mean diameter at breast height was from 11.7 to 14.7cm. Distribution pattern of diameter at breast height was bell-shaped type. Distribution patterns of tree height were bell-shaped, two bell-shaped and J-shaped type. Structures of layer were mono-story, two stories and multi-stories types. Tree height (H)-diameter at breast height (D) curve represents a hyperbolic regression, 1/H=0.5874/D^<0.82>+0.0497. It will be estimated the difference of tree height was caused of difference of soil types.
