초록

This study analyzes the flora researched from 22 uninhabited islands in Buan-gun and Gochanggun of Jeollbukdo Province. In total there were 199 taxa of vascular plants, 65 families 139 genera 173 species, 1 subspecies, 23 varieties, 2 forms, and they were studied. Among these were 70 types of Jakeuntanchi-do including 35 families 58 genera 57 species, 11 varieties, 2 forms, 69 taxa of Gae-do, 51 types of Suribawi, 45 varieties of yeol-do and 43 taxa of Tanjunggeum-do in the order of the number of types. However, there was not a single plant found in Moyeo2-do, Moyeo3-do and Ganyeo-do since the environment there only consists of rocky terrains in which vegetation is hard to form.
In order to analyze the characteristic of each flora, samples from the Chungnam province was collected at a higher latitude where as in the Jeonnam province, plants in the lower latitude were examined. The districts involved concerns Buangun and Gochanggun including the 22 uninhabited islands. In Buangun and Gochanggun only a minority species of Evergreen Broad leaved Trees such as the Camellia japonica and Eurya japonica which tend to be dispersed were examined. Compared to Goheung, Yeosu and Younggwang where there are diverse warm temperate species, Bunangun and Gochanggun have a less variety of vegetation. In addition a high number different vegetation was found in the uninhabited islands of Chungnam province and Gunsan city, where artificial disturbance is not severe compared to other study areas.
A total of 21 taxa of Korean endemic plants were researched in the study area, which involves the South Province of the Korea. A relatively small number of Korean endemic plants, 1.96% of 1,071 Korean endemic plants (Kim, 2000), inhabit this region. The number of naturalized plants was relatively small as well, consisting of 8 taxa, 4.39%(naturalized ratio) of the whole 182 species researched in the 22 uninhabited islands and 2.49%(urbanization index) of the 321 Korean naturalized plants species. Thus, vegetation conservation and restoration measures are needed in order to protect the vegetations of Buangun, Gochanggun and the 22 uninhabited islands from human interference and disturbance.
In conclusion this study was designed to identify indigenous species dispersed in Buangun, Gochanggun and the 22 uninhabited islands. The purpose of this study was to provide primary data on examining indigenous species in order to contribute to the conservation and restoration of flora and vegetation.
