Abstract
1998년 3월부터 2003년 9월까지 남해도 및 인접도서를 포함하는 남해군의 삼림식생에 대해 Z.-M.방법에 의한 식물사회학적 조사를 실시하였다. 그 결과 본 조사지역의 삼림식생은 신갈 나무군락(전형하위군락, 철쭉꽃하위군락), 졸참나무군락(전형하위군락, 당단풍하위군락), 굴참나무군락(전형하위군락, 굴피나무하위군락), 상수리나무군락, 서어나무군락, 소사나무군락, 때죽나무군락, 느티나무군락, 히어리군락, 소나무군락(전형하위군락, 진달래하위군락, 서어나무하위군락), 곰솔군락(전형하위군락, 사스레피나무하위군락), 산철쭉군락, 편백식재림, 사방오리식재림, 리기다소나무식재림, 아까시나무식재림, 삼나무식재림 등 총 12군락, 11하위군락, 5식재림으로 구분되었다. 본 조사지역 삼림의 토양분석결과 삼림토양의 pH는<TEX>$4.2\sim5.4$</TEX>의 범위를 나타내었으며, 함수량은 유기물함량과 유의성이 높은 가운데 산철쭉군락이 가장 높고, 소나무군락이 가장 낮게 나타났다. 유기물함량은 신갈나무군락, 소사나무군락, 졸참나무군락에서 비교적 높게<TEX>$(15.8\sim19.1%)$</TEX> 나타났고, 상수리나무군락, 히어리군락, 곰솔군락에서는 낮게<TEX>$(3.3\sim5.4%)$</TEX> 나타났다. 식재림은 대부분 낮았으며. 리기다소나무식재림(2.8%)과 삼나무식재림(5.6%)이 가장 낮았다. 치환성 양이온(<TEX>$K^+$</TEX>, <TEX>$Ca^{2+}$</TEX> and <TEX>$Mg^{2+}$</TEX>)사이에는 높은 상관관계가 있는 것으로 나타났다. The forest vegetation of Namhae-gun was investigated using the methodology of the Z.-M. school of phytosociology from March, 1998 to September, 2003. The forest vegetation was classified into 12 communities, 11 subcommunities, 5 afforestations as follows : Quercus mongolica community(typical subcommunity, Rhododendron schlippenbachii subcommunity), Ouercus serrata community(typical subcommunity, Acer pseudo-sieboldianum subcommunity), Ouercus variablis community(typical subcommunity, Platycarya strobilacea subcommunity), Quercus acutissima community, Carpinus laxiflora community, Carpinus coreans community, Styrax japonica community, Zelkova serrata community, Corylopsis coreana community, Pinus densiflora community(typical subcommunity, Rhododendron mucronulatum subcommunity, Carpinus laxiflora subcommunity), Pinus thunbergii community(typical subcommunity, Eurya Japonica subcommunity), Rhododendron yedoense var. poukhanense community, Chamaecyparis obtusa afforestation, Alnus firma afforestation, Pinus rigida afforestation, Robinia pseudo-acacia afforestation, Cryptomeria japonica afforestation. The soil pH of the study area was ranged from 4.2 to 5.4, and soil moisture content was strongly related to organic matter content. The Corylopsis coreana community contained the highest soil moisture content, whereas Pinus densiflora community contained the lowest one. The content of organic matter were <TEX>$15.8\sim19.1%$</TEX> in the Quercus mongolica, Carpinus coreans and Ouercus serrata communities, <TEX>$3.3\sim5.4%$</TEX> in the Quercus acutissima, Corylopsis coreana and Pinus thunbergii communities, and <TEX>$2.8\sim5.6%$</TEX> in the Pinus rigida and Cryptomeria japonica afforestation. There is significant correlation among the contents of cations(<TEX>$K^+$</TEX>, <TEX>$Ca^{2+}$</TEX> and <TEX>$Mg^{2+}$</TEX>).
