Abstract
The study was carried out to determine the frequency distribution of trees by diameter classes according to the method of Bruce and Reineke's alignment with the data of pitch pine (Pinus rigida Miller) and Italian poplar (Populus euramericana Guinier) which are prepared for the purpose of yield table construction. The results obtained are summarized as follows: 1. All through the tree species studied, when their diameters were larger, their distribution range became wider, while the percentage of their distribution frequency became lesser. 2. As for frequency percentage of trees in an average D.B.H. of stands, it became smaller when average D.B.H. of the stand is larger: the percentage of pitch pine stand is 36.2 and that of Italian poplaris 29.0. 3. In case of smaller D.B.H. under the average, the larger their D.B.H. became, the lesser the cumulative frequency percentages became.
본(本) 연구(硏究)는 수확표(收穫表)를 조제(調製)하기 위(爲)하여 모집(募集)한 리기다소나무와 이태리포플러의 자료(資料)를 갖고 Bruce와 Reineke가 발표(發表)한 직렬도법(直列圖法)에 의(依)하여 포고직경별(胞高直徑別) 본수(本數)의 분배(分配)를 구명(究明)하였다. 그 결과(結果)는 다음과 같이 요약(要約)된다. 1. 각수종(各樹種) 모두 대경목(大徑木)일수록 임분(林分)의 직경범위(直徑範圍)는 넓어지며 각직경계(各直徑階)의 전본수(全本數)에 대(對)한 백분율본수(百分率本數)는 작아진다. 2. 임분(林分)의 평균직경(平均直徑)과 동일(同一)한 포고직경(胞高直徑)을 가진 임분(林分)의 전본수(全本數)수에 대(對)한 백분율(百分率)은 직경목(直徑木)일수록 적어지며 평균적(平均的)으로 리기다소나무임분(林分)은 36.2%, 이태리포플러임분(林分)은 29.0%이다. 3. 임분(林分)의 평균직경(平均直徑)보다 작은 적산본수백분율(積算本數百分率)은 대경목(大徑木)일수록 적어지며 평균적(平均的)으로 리기다소나무임분(林分)은 73.7%, 이태리포플러임분(林分)은 75.7%이다.
