Abstract
This study was carried out to know the difference in growth and degree of competition between individuals of thinned and unthinned larch stands. Annual increment and total growth were obtained from the cores sampled at breast height. The correlation between adjacent individual trees was investigated. 1) The correlation between radius growth and basal area was used to estimated the degree of competition among individual trees. 2) In estimating the degree of competition the correlation between two individual trees was better method than others. 3) Up to 9 years after planting no competition between individual trees occurred and the Night positive correlation was shown. 4) High degree of competition was observed at age of 10 years after the planting, as the correlation coefficient was getting smaller. 5) The degree of competition among individual trees increased with increase of the growth of total stand.
본(本) 조사(調査)는 낙엽송(落葉松) 인공성림지(人工成林地)에서, 간벌(間伐)이 가(加)해진 임분(林分)과 가(加)해지지 않은 고정표본구(固定標本區)에서 임목(林木) 개체간(個體間)의 생장상관(生長相關)을 가지고 개체간(個體間)의 경쟁효과(競爭効果)를 알아 보기 위하여 실시(實施)하였다. 1) 조사(調査)는 흉고부위(胸高部位)에서 increment borer에 의하여 채취(採取)된 core에서 연년생장(連年生長)과 총생장(總生長)을 조사(調査)하고 이에 의하여 인접임목개체간(隣接林木個體間)의 상관관계(相關關係)를 계산(計算)해서 확인(確認)하였다. 2) 경쟁효과(競爭効果)의 추정방법(推定方法)은 (1)
