본 조사는 2017년 4월부터 2018년 10월까지 본 조사와 2019년, 2020년 2차례 추가조사를 통하여 다도해해상국립공원 주변지역을 중심으로 상록활엽수림의 식생 현황을 조사하였다. 다도해해상국립공원에서 조사된 상록활엽수림 주요군락은 구실잣밤나무군락, 후박나무군락, 붉가시나무군락 등을 포함하여 33개 군락이, 상록활엽수림과 혼생하는 군락은 낙엽활엽수림에서는 굴참나무-동백나무군락, 굴참나무-사스레피나무군락, 상록침엽수림에서는 소나무-후박나무군락, 소나무-동백나무군락, 소나무-붉가시나무군락, 소나무-사스레피나무군락, 곰솔-구실잣밤나무군락, 곰솔-동백나무군락, 곰솔-사스레피나무군락, 곰솔-우묵사스레피군락, 곰솔-붉가시나무군락, 곰솔-참식나무군락, 곰솔-후박나무군락, 곰솔-생달나무군락, 산지습성림으로는 고로쇠나무-참식나무군락 등을 포함하여 15개 군락이 나타났으며, 전체적으로 48개 군락이 나타났다. 이중에서 동부지역인 나로도지구, 금오도지구, 소안·청산지구에서는 35개 상록활엽수림 군락이 조사되었고, 서부지역인 조도지구, 비금·도초지구, 흑산·홍도지구에서는 29개 상록활엽수림 군락이 조사되었다. 다도해해상국립공원 주요 36개 도서 가운데 가장 많이 분포한 상록활엽수림은 구실잣밤나무군락으로 23개 도서(63.8%), 곰솔-사스레피나무군락 21개도서(58.3%), 곰솔-동백나무군락 10개 도서지역에서 비교적 넓게 분포하고 있었다. 그 외에 후박나무군락(9개), 동백나무군락(8개), 구실잣밤나무-곰솔군락(6개), 후박나무-동백나무군락(4개) 등이 나타났다. 또한 다도해해상국립공원 상록활엽수림을 조사하고 과거자료(1995년, 2009년)와 비교하면서 상관에 의한 식생을 정리하였다. 다도해해상국립공원은 서남해안 도서중에서도 비교적 자연경관이 뛰어난 지역이므로 주요 도서별 식생 특성에 따라서 효율적인 관리대책을 수립함에 있어서, 각 도서별 식생 특성에 따라서 관리방안을 수립하여야 한다.

This survey investigated the vegetation status of evergreen broad-leaved forests around the area around Dadohaehaesang National Park through the main survey from April 2017 to October 2018 and two additional surveys in 2019 and 2020. The major communities of evergreen broad-leaved forests investigated in Dadohaehaesang National Park were 29 colonies, including the Castanopsis cuspidata var. sievoldii community, Machilus thunbergii community and Quercus acuta community, and the mixed with evergreen broad-leaved forest were Quercus variabilis-Camellia joponica community and Quercus variabilis-Eurya japonica community. In the evergreen coniferous forest, Pinus densiflora-Machilus thunbergii community, Pinus densiflora-Camellia joponica community, Pinus densiflora-Quercus acuta community, Pinus densiflora-Eurya japonica community, Pinus thunbergii-Castanopsis cuspidata var. sievoldii community, Pinus thunbergii-Camellia joponica community, Pinus thunbergii-Eurya japonica community, Pinus thunbergii-Eurya emarginata community, Pinus thunbergii-Quercus acuta community, Pinus thunbergii-Neolitsea sericea community, Pinus thunbergii-Machilus thunbergii community, Pinus thunbergii-Cinnamomum japonicum community, Acer pictum var. mono-Neolitsea sericea community, 15 colonies appeared, and 44 colonies in total. Among them, 33 evergreen broad-leaved forest communities were investigated in the eastern regions of Narodo district, Geumodo district, Soan district and Cheongsan district, and 28 evergreen broad-leaved forest communities in the western regions of Jodo district, Bigeum district and Docho district, and Heuksan district and Hongdo district. Among the 36 islands in the survey area, the evergreen broad-leaved forest was relatively large in 23 islands(63.8%) of Castanopsis cuspidata var. sievoldii community, 21 islands(58.3%) of Pinus thunbergii-Eurya japonica community, and 10 islands of Pinus thunbergii-Camellia joponica community. It was widely distributed. In addition to this, there were 9 colonies of Machilus thunbergii community, 8 colonies of Camellia joponica community, 6 colonies of Castanopsis cuspidata var. sievoldii-Pinus thunbergii community and 4 colonies of Machilus thunbergii-Camellia joponica community. It was distributed relatively widely in the region. In addition, the evergreen broad-leaved forest in Dadohaehaesang National Park was surveyed and compared with past data (1995, 2009), and vegetation by correlation was summarized. Dadohaehaesang National Park is a region with relatively excellent natural scenery among the southwestern coastal islands. Therefore, in establishing efficient management measures according to the vegetation characteristics of each island, management plans should be established according to the vegetation characteristics of each island.
