초록

본 연구는 우리나라에 분포하고 있는 상수리나무림을 대상으로 식물사회학적 조사를 통하여 상수리나무림의 군집을 분류하고 각 군집간의 상관관계, 잠재자연식생, 입지에 따른 상수리나무의 분포 양상 등을 분석하여 한국 상수리나무림의 특성을 밝히고자 한다. 1. 한국 상수리나무림의 군집구분은 1군단, 3군집, 3아군집, 3전형아군집으로 유형화되었다. I. 상수리나무군단(Quercion acutissimae) A. 상수리나무-졸참나무군집(Quercetum serrato-acutissimae ass. nov.) A-1. 갈참나무아군집(Quercetum serrato-acutissimae quercetosum subass. nov.) A-2. 전형아군집(Quercetum serrato-acutissimae typicum subass. nov.) B. 상수리나무-신갈나무군집(Quercetum mongolico-acutissimae asso. nov.) B-1. 갈참나무아군집(Quercetum mongolico-acutissimae quercetosum subass. nov.) B-2. 전형아군집(Quercetum mongolico-acutissimae typicum subass. nov.) C. 상수리나무-서어나무군집(Carpino-Quercetum acutissimae asso. nov.) C-1. 갈참나무아군집(Carpino-Quercetum quercetosum subass. nov.) C-2. 전형아군집(Carpino-Quercetum typicum subass. nov.) 2. DECORANA에 의한 요인분석 결과 상수리나무-졸참나무군집은 저지대 산지, 상수리나무-신갈나무군집은 상대적으로 해발이 높은 지역의 산지대, 상수리나무-서어나무군집은 주로 계곡부에 형성되어 있음을 입증하고 있다. 그러나 각 군집들이 서로 혼재되어 있는 경우가 많아 그다지 명료하게 나타나지는 않았다. 이러한 결과는 상수리나무림의 대부분이 저지대 및 농경지 주변의 교란요인이 심한 지역에 분포하고 있기 때문으로 사료된다. 3. 상수리나무림의 잠재자연식생을 추정한 결과는 다음과 같다. 1) Quercetum serrato-acutissimae asso. nov.$\rightarrow$Quercus serrata-Quercus aliena Community$\rightarrow$Quercus serrata Community 2) Quercetum mongolico-acutissimae ass. nov.$\rightarrow$Quercus mongolica-Quercus aliena Community$\rightarrow$Quercus mongolica Community 3) Carpino-Quercetum acutissimae asso. nov.$\rightarrow$Carpinus laxiflora-Quercus aliena Community$\rightarrow$Carpinus laxiflora Community

This study has targeted Quercus acutissima forests in Korea and has classified the association between Quercus acutissima forests by using the phytosociological method. In addition, the correlation between each association, distribution, potential natural vegetation, and aspect of Quercus acutissima forest according to location have been analyzed to examine the characteristics of the Korean Quercus acutissima forests. Through factor analysis of DECORANA, it was revealed that Quercetum serrato-acutissimae forms in the basal zones of mountains, Quercetum mongolico-acutissimae is formed in the highlands, in the relatively high mountain area, and Carpino-Quercetum acutissimae is mainly distributed in valleys. However, this phenomenon is not very obvious, as each association structure is often mixed up. This result is caused by inhomogeneity of the Quercus acutissima forests, and most of it is distributed in basal zones or around farmlands where there are severe disturbance factors. The proposed potential natural vegetation of the Quercus acutissima forests in Korea is as follows; Quercetum serrato-acutissimae$\rightarrow$Quercus aliena-Quercus serrata community$\rightarrow$Quercus serrata community, Quercetum mongolico-acutissimae$\rightarrow$Quercus aliena-Quercus mongolica community$\rightarrow$Quercus mongolica community, Carpino-Quercetum acutissimae$\rightarrow$Quercus aliena-Carpinus laxiflora community$\rightarrow$Carpinus laxiflora community.
