Abstract
1. This is a study on the utilization volume of the 94 native Korean red pines in Kwangyan Forests. 2. The formulas which derived by the above investigation are follows. a. Hight growth curve ; $H=4.76+0.125D+0.0026D^2$ b. Cubic volume formula; $V=0.0000839D^{2.3}\;H^{0.2}$ c. The relation between utilization volume and log length ; Vu=0.1708-0.0230L d. The percentage of utilization, when length was 2 meters; $P=27.37\;D^{0.3648}$ e. The number of 2 meter long timbers; $N=0.0863D^{1.16}$ f. The equation of the utilization timber volume when log length was 2 meters; $Vu=0.0000159D^2\;H^{1.3}$ 3. As a conclusion, it was found that the utilization volume in the case of 2 meter log, was most greater than the others.
광야소재(光陽所在) 천연성(天然性) 소나무에 대(對)하여 조사(調査)한 결과(結果)는 다음과 같다. 1. 수고성장(樹高成長) $H=4.76+0.125D+0.0026D^2$ 2. 소나무의 입목재적식(立木材積式)은 $V=0.0000839D^{2.3}H^{0.2}$ 3. 이용재적(利用材積)과 재장간(材長間)에는 Vu=0.1708-0.0230L 4. 이용율(利用率)은 재장(材長)을 2m로 했을 때 $P=27.37D^{0.3648}$ 5. 조재가능(造材可能)한 2m 재장(材長)의 수(數)는 $N=0.0863D^{1.16}$ 6. 이용재적식(利用材積式)은 재장(材長)을 2m로 했을 경우 $Vu=0.0000159D^2H^{1.3}$ 위의 결과(結果)는 종합적(綜合的)으로 재장(材長)을 2m 후 조재(造材)할 때 이용재적(利用材積)이 가장 많다는 것을 명백(明白)히 하였다.
