본 연구는 부산시 나무섬의 생태관광 자원화와 생물종 다양성 보존을 위한 생태적 자료를 제공하고자 식생구조와 관속식물상을 분석하였다. Cluster분석한 결과 나무섬은 3개의 군집으로 분류되었다. 수종간의 상관관계는 도깨비쇠고비와 털머위, 밀사초; 큰천남성과 미국자리공, 곰솔; 억새와 보리밥나무가 높은 정의상관관계가 나타났으며, 갯 기름나물과 미국자리공은 부의 상관관계로 이질적인 지위로 나타났다. 종다양도의 경우 1.4507~1.4962, 최대 종다양도는 1.5798~1.6628, 균재도는 0.8998~0.9183로 나타났다. 전체 출현한 관속식물은 42과 70종 5변종 1품종으로 나타났으며, 귀화도는 13.2%이며 식물구계학적 1등급 식물의 경우 15과 17종, 3등급식물의 경우 3과 4종이 나타났다. This study was carried out to provide ecological resources which is need for ecotourism resource, species diversity at Namu island in Busan. As a result of analyzing cluster of the Namu island was divided into three different community. There were positive correlation between Cyrtomium falcatum and Farfugium japonicum, Carex boottiana; Arisaema ringens and Phytolacca americana, Pinus thunbergii ; Miscanthus sinensis and Elaeagnus macrophylla and weak negative correlation were showed between Peucedanum japonicum and Phytolacca americana. Species diversity index(H') of investigated groups ranged from 1.4507~1.4962, H' max ranged from 1.5798~1.6628, Evenness(J') ranged from 0.8998~0.9183. The vascular plants were listed 70 taxa; 42 families, 5 varieties and 1 form. Percent of exotic plant species was 13.2% and The specific plants which is categorized to Degree by Ministry of Environment appeared as 15 taxa, Degree I was 15 families 17 species and Degree Ill was 3 families 4 species.

This study was intended for Fagus engleriana stand in Is. Ulleung where the disturbance of vegetation has been caused by the exploitation and the increase of tourists. For the effective conservation and management on this issue, this study was conducted provide basic data. The sixteen study sites (20×20m) were installed in the dominant Fagus engleriana stand and the base environment and vegetation were investigated. The Fagus engleriana stand was classified into two groups, The Fagus engleriana stand was classified into two groups, community A is Fagus engleriana-Sorbus amurensis and community B is Fagus engleriana-Acer pictum subsp. Mono by cluster analysis and community A were nothing signigicant by indicator species analysis. Community B were Eight species (Tsuga sieboldii, Camellia japonica, Dystaenia takesimana ect.) significant by indicator species analysis. The diameter class of 16cm to 25cm was 53.7% in population structure of Fagus engleriana, which was the highest and showed inverse J-distribution. Species diversity index (H`) of investigated woody layer group ranged from 0.99 to 2.05 and that of under layer group ranged from 1.75∼2.59. According to Non-metric Multidimensional Scaling (NMS) analysis, the woody layer was divided into community A developed in the region having relatively high sand content at high altitudes and community B formed at the place having relatively high clay content at low altitudes. Then this classification was significant through Multi-Response Permutation Procedures (MRPP) analysis. The distribution of understory vegetation through Detrended Correspondence Analysis (DCA) was induced by the silt content and cover degree of vegetation layer.
