of Taiwanhannoki (Alnus formosana Makina), from the view point of forest measurement. The results of the study are as follows : 1. Green weight of stem The relations of the diameter at breast height, the tree height and the volume to the green weight of stem are expressed by following equations. 1). y=0.3869x^\u003c2.1505\u003e where y : green weight of stem (kg) x : diamete at breast height (cm) 2). y=0.0005x^\u003c4.3519\u003e where y : green weight of stem (kg) x : tree height (m) 3). y=0.6789+907.5358x where y : green weight of stem (kg) x : stem volume (m^3) Namely, the relations of the diameter at breast height and the tree height to the green weight of stem are expressed by a curvilinear regression, and the relation with the volume is expressed as a rising linear line. And the green weight increases with the increase of the diameter at breast height, the tree height and the volume. The equations are in conformity with the actual measurements, and the green weight has a high correlation with each factor. Particularly, the relation with the volume shows fairly a perfect correlation as seen from 0.999 of the coefficient of correlation. Therefore, it is considered that it is possible to estimate the green weight of stem from each measurement factor. 2. Mean specific gravity The mean specific gravity has a high correlation with the average specific gravity at breast height, and it increases with the increase of the average specific gravity at breast height. And the mean specific gravity is almost constant in spite of the increase of the diameter at breast height, the tree height and the volume. 3. Dry weight of stem The regression equations of the relations of each measurement factor to the dry weight are shown as follows : 1). y=0.1801x^\u003c2.1647\u003e where y : dry weight of stem (kg) x : diameter at breast height (cm) 2). y=0.0002x^\u003c4.3894\u003e where y : dry weight of stem (kg) x : tree height (m) 3). y=-1.1323+450.9167x (r=0.997) where y : day weight of stem (kg) x : stem volume (m^3) 4). y=12.2000+2379.9935x (r=0.964) where y : dry weight of stem (kg) x : branch volume (m^3) 5). y=-1.5491+0.4974x (r=0.999) where y : dry weight of stem (kg) x : green weight of stem (kg) 6). y=9.8618+2.0658x (r=0.969) where y : dry weight of stem (kg) x : green weight of branches and leaves (kg) Namely, the relations with the diameter at breast height and the tree height show a curvilinear regression and the relations with the volume, the branch volume, the green weight and the weight of branches and leaves show a rising linear regression.", "subitem_description_type": "Other"}, {"subitem_description": "The regression equations are in conformity with the actual measurements, therefore, it is considered that it is possible to estimate the dry weight from each measurement factor. 4. Growth of dry weight 1). The range and the mean of the current annual growth of the dry weight per hectare are from 31.810 ton to 18.120 ton and 24.956 ton respectively. The precision of estimate is 27.46% in probability 95%. 2). The dry weight per hectare is 160.783 ton, and the volume per hectare is 335.84m^3. Therefore, the mean specific gravity of the stand is 0.479ton/m^3. 3). The growth percentage of the dry weight is 15.52% which is slightly lower than 15.87% in the volume growth. 5. Comparison of the growth of the volume and dry weight 1). The diameteres at breast height of the average volume tree, the average green weight tree, the average dry weight tree and the average basal area tree are 15.4cm, 15.3cm, 15.3cm, and 15.4cm respectively, differing by only 0.1cm. As this much of difference is considered to be an error in measurement, it may well be considered that the diameteres at breast height of each factor agree one another. 2). The interrelation among the green weight of stem, the dry weight of stem without bark, the dry weight of stem with bark and the stem volume to the diameter at breast height is nearly shown by a parallel lines. 3).
