초록

This study was conducted to provide ecological basic data that use to establish environmental conditions for cultivation of wild vegetables in 2016-2018. Therefore, we investigated the vegetation structure and the correlationbetween the community structure andtheenvironmental factors for natural habitats ofwild vege- tables(Aster glehni, Allium ochotense, and Aruncus sylvester) distributed in Ulleungdo. As a result of pop- ulation and gradient analysis, the vegetation was classified into Aster glehni community, Allium ochotense community, and Aruncus sylvester community. We confirmed that the classification by population analysis was consistent with that by TWINSPAN method, suggesting that they were complemented each other. The importance value of Aster glehni was the highest in all communities, followed by Aruncus sylvester, Alliumochotense,Hydrangeapetiolaris,Dryopteriscrassirhizoma,Asperula ldorata,Phrymaleptostachyavar. asi- atica, Disporum viridrescens, Hedera rhombea, Anthriscus sylvestris, and Hepatica maxima. According to the results of DCCA ordination analysis, among those communities, the Aster glehni community was dis- tributed in soil where the nutrition including T-N and O.M. were intermediate.
