Abstract
The vegetation of common Cryptomeria (Cryptomeria japonica D. Don) stands planted in Chonnam- province was investigated to obtain the fundamental informations for evaluation of suitable site and the improvement of managing method of the Cryptomeria stands in this region. The results investigated were summarized as follows; 1) The growth condition of common Cryptomeria planted 21-25-year-old stands was similar that of same species growing in Akidaken-district in Japan, while the growth condition of 51-58-year-old stands was not so good as that of Japanese. 2) Total number of plant species was 256. The number of floristic composition varied in the range of 42-99- species, which should be mere than those of Japanese. 3) The investigated sites were located in temperate southern part and in subtropic northern part of Korean peninsular. The types of understory vegetation were classified from I to IV class. 4) From the results of high max. possible diversity (H' max), and dominance (1-J') and from the low simple dominance (
한국남부지역(韓國南部地域)에서 조림(造林)되고 있는 삼나무의 조림적지(造林適地)의 판정(判定) 및 시업방법(施業方法)의 개선(改善)에 필요(必要)한 기초(基礎)를 얻고자 삼나무 임분(林分)의 식생(植生)을 조사분석(調査分析)한 결과(結果)는 다음과 같다. 1) 조사지역(調査地域) 및 임분(林分)의 환경조건(環境條件)은 일본추전현지역(日本秋田縣地域)에 비교(比較)하면 21~25년생(年生) 임분(林分)은 동등(同等)하였으나 51~58년생(年生) 임분(林分)은 불량(不良)한 생육상태(生育狀態)이었다. 2) 총출현종수(總出現種數)는 256종(種)이었고, 조성종수(組成種數)는 42~99종(種)으로 일본(日本)에서 보다 많은 편(便)이나 상한수(上限數)는 같았다. 3) 온대남부(温帶南部) 및 난대북부림대(暖帶北部林帶)에 속(屬)하며 표(表) 4 와 같이 I~IV 급(級)의 임상형(林床型)으로 구분(區分)하였다. 4) 최대종다양도(最大種多樣度)(H' max)와 우점도(優占度)(1-J')는 높았고 Simpson 종다양도(種多樣度)(
