Abstract

The purpose of this study is to understand the vegetation characteristics of ridges (Gyeongsusan-Seonunsan-Gaeipalsan) in the Seonunsan Provincial Park and to establish reference information for the management of the park in the future. We designated 62 plots with the area of $100m^2$ were installed and analyzed them to investigate the vegetation characteristics. The results of community classification based on TWINSPAN showed seven categories of vegetation communities in the surveyed region: Quercus dentata-Deciduous broad-leaved Community, Quercus variabilis-Pinus thunbergii-Quercus serrata Community, Pinus densiflora Community, Deciduous broad-leaved Community-I, Carpinus tschonoskii-Castanea crenata-Quercus aliena Community, Deciduous broad-leaved Community-II, and Carpinus tschonoskii-Carpinus laxiflora Community. In the vegetation of Seonunsan Provincial Park, coniferous trees such as Pinus thunbergii and Pinus densiflora have been gradually losing their population as part of ecological succession to deciduous broad-leaved trees such as Quercus spp., Carpinus tschonoskii, and Carpinus laxiflora. Moreover, Carpinus turczaninowii, Mallotus japonicus, and others were identified as vegetation reflecting the geographical characteristics of the region neighboring the west coast. The estimated age is 30-60 years, and the oldest tree Pinus densiflora is 63-years old. The index of diversity ($100m^2$) was 0.7942 for Carpinus tschonoskii-Carpinus laxiflora Community, 0.8406 for Carpinus tschonoskii-Castanea crenata-Quercus aliena Community, 0.8543 for Quercus dentata-Deciduous broad-leaved Community, 0.9434 for Quercus variabilis-Pinus thunbergii-Quercus serrata Community, 0.9520 for Deciduous broad-leaved Community-I, 0.9633 for Pinus densiflora Community, and 1.0340 for Deciduous broad-leaved Community-II in the ascending order.

본 연구는 선운산도립공원의 능선부(경수산~선운산~개이빨산) 식생 특성을 파악하여 향후 도립공원 관리를 위한 기초자료를 구축하고자 수행하였다. 식생 특성을 알아보기 위해 $100m^2$ 크기의 조사구 62개소를 설치하여 조사 분석하였다. TWINSPAN에 의한 군락분류 결과, 떡갈나무-낙엽활엽수혼효군락, 굴참나무-곰솔-졸참나무군락, 소나무군락, 낙엽활엽수혼효군락-I, 개서어나무-밤나무-갈참나무군락, 낙엽활엽수혼효군락-II, 개서어나무-서어나무군락 총7개 군락으로 분리되었다. 선운산도립공원의 식생은 곰솔과 소나무 등의 침엽수는 점점 세력을 잃어가고 있는 반면, 굴참나무, 졸참나무, 갈참나무 등의 낙엽성 참나무류와 개서어나무와 서어나무의 세력이 왕성해지고 있어 낙엽활엽수군락으로의 생태적 천이가 진행되고 있는 것으로 판단되다. 또한 서해와 접하고 있는 지리적 특성을 반영한 식생으로 소사나무, 예덕나무 등이 확인되었다. 본 조사지역의 임령은 30~60년으로 추정되었으며, 추정연령이 가장 오래된 나무는 소나무로 약 63년생으로 조사되었다. 종다양도지수($100m^2$)는 0.7942(개서어나무-서어나무군락) ${\rightarrow}$ 0.8406(개서어나무-밤나무-갈참나무군락) ${\rightarrow}$ 0.8543(떡갈나무-낙엽활엽수혼효군락) ${\rightarrow}$ 0.9434(굴참나무-곰솔-졸참나무군락) ${\rightarrow}$ 0.9520(낙엽활엽수혼효군락-I) 0.9633(소나무군락) ${\rightarrow}$ 1.0340(낙엽활엽수혼효군락-II) 순으로 높았다.
