To investigate the distribution of vascular plants growing at Halmibong(1,026m) and Gusibong(1,014m) in Baekdutrail, we surveyed from March in 2013 to March in 2014. The flora of Haimibong and Gusibong in Baekdu trail were found to be; 528 taxa; 95 families, 287 genus, 454 species, 4 subspecies, 59 varieties, 11 forma. Rare plants were found to be; 15 taxa, 10 families, 14 genus, 13 species, 2 varieties. Among them EN degree was found to be 1 species(Rhododendron tschonoskii Maxim.), VU degree; 2 species(Scorzonera albicaulis Bunge, Lilium cernuum Kom.), LC degree; 12 species(Abies koreana Wilson, Coreanomecon hylomeconoides Nakai, Viola albida Palib. etc.) respectively. In all surveyed areas, a total of 15 taxa(Heloniopsis koreana Fuse, N.S.Lee & M.N. Tamura etc.) were found to be endemic to Korea. Distribution of floristic special plants in the surveyed areas were found to be divided into five classes (class I~V). The floristic special plants found in surveyed areas were 2 taxa of grade V, 6 taxa of grade IV, 12 taxa of grade III, respectively. The naturalized plants were investigated as 23 taxa; Rumex crispus L., Amorpha fruticosa L., Veronica arvensis L. etc..

To investigate the vegetation structure of mountain ridge from Bubong to Poamsan, 16 plots$(400m^2)$ set up with random sampling method were surveyed. Three groups Quercus mongolica-Pinus densiflora community, Quercus variabilis-Pinus densiflora-Quercus mongolica community were classified by cluster analysis. Quercus mongolica was found as a major woody plant species in the ridge area from Bubong to Poamsan, and partly in lower elevation was occupied by Quercus variabilis and Pinus densiflora. High positive correlations was proved between Lespedeza maximowixcii and Pinus koraiensis, Fruxinus sieboidiana and Rhododendron mucronulatum, Acer mono and Weigela subsessilis, and relatively high negative correlations was proved between Symplocos chinensis for. pilosa and Fraxinus sieboldiana, Rhododendron mucronulatum Species diversity(H') of investigated groups were ranged $0.9066\~1.0821$, and it was relatively low compared to those of mountain ridge area of other national parks.

비무장지대(DMZ)는 군사적 활동 외에 일반인에 의한 접근이 엄격히 통제되어 자연적으로 생물들이 보호되어 왔으며, 한반도의 거대한 동 서 생태축으로서 그 중요성이 매우 높다. 본 연구는 경기도 연천군지역의 비무장지대 및 민통선지역에 분포하는 자원식물의 현황을 파악하고 희귀식물, 한국특산식물 등 주요 유용자원식물의 보전과 관리에 기초자료를 제공하고자 실시하였다. 연구대상지에 분포하는 자원식물은 74과 168속 192종 4아종 26변종 5품종으로 총 227분류군으로 우리나라에 분포하는 관속식물 4,881(국립수목원, 2007)분류군의 4.66%로 나타났다. 각 과별 구성종의 출현비율을 살펴보면 국화과 36분류군으로 가장 다양하게 출현하였다. 연구대상지내에 분포하는 희귀식물은 쥐방울덩굴(Aristolochia contorta Bunge)로 1분류군이 확인되었으며, 한국특산식물은 키버들(Salix koriyanagi Kimura), 병꽃나무(Weigela subsessilis (Nakai) L.H.Bailey), 은사시나무(Populus tomentiglandulosa T. B. Lee)로 3분류군, 귀화식물은 단풍잎돼지풀(Ambrosia trifida L.), 족제비싸리(Amorpha fruticosa L.), 아까시나무(Robinia pseudoacacia L.) 등 등 17분류군으로 나타났다. 연구결과 전체적으로 다양한 식물종이 확인되지는 않았으며, 일부 구간에는 가시박(Sicyos angulatus L.), 돼지풀(Ambrosia artemisiifolia L.), 단풍잎돼지풀(Ambrosia trifida L.) 등 생태계교란 야생식물이 폭넓게 분포하고 있는 것을 확인할 수 있었다.

This study presents the flora of vascular plants on Oenarodo Island, located in Goheung-gun, Jeollanam-do, Korea. A list of vascular plants was created based on the herbarium of the National Biological Resource Center (NIBR) and the Daejeon University Biology Department herbarium (TUT) collected from field surveys. Based on specimens collected in the field during 21 separate field trips amounting to a total of 21 days conducted between March of 2015 and October of 2017, there are 587 taxa on Oenarodo Island, consisting of 122 families, 364 genera, 538 species, six subspecies, 41 varieties, and two forms. Among the collected plants, those endangered were four taxa, those endemic were 14 taxa, floristic regional indicator plants specially designated by the Ministry of the Environment amounted to 137 taxa, and those naturalized amounted to 46 taxa.

This study was carried out to investigate the distribution status and invasional characteristics of the naturalized plants. The vascular plants in these areas were consisted of total 381 taxa: 81 families, 234 genera, 295 species, 2 subspecies, 66 verieties, 18 forms. Among the investigated vascular plants, naturalized plants (Sicyos angulatus, Barbarea vulgaris, Thlaspi arvense, Amorpha fruticosa, Trifolium pratense, Ambrosia artemisiifolia, Ambrosia trifida, Aster pilosus, Rumex acetosella etc.) were 41 taxa. The Naturalization Index (NI) was 10.70% and the Urbanization Index (UI) was 15.30% at Chuncheon city. The Invasion Index was 63.41% at urban river and 97.56% at stream high, 19.51% at urban forest area.

The present study was undertaken to classify and describe the spring naturalized plant communities in old-Andong city by the methodology of the ZM school of phytosociology. As a result, the vegetation was classified into the six communities and two subcommunities: A. Bromus tectorum community A-a. Bromus japonicus subcommunity, A-b. Melica onoei subcommunity; B. Poa pratensis community; C. Rumex crispus community; D. Oenothera lamarckiana community; E. Ambrosia artemisiifolia var. eiatior community; F. Rumex conglomeratus community. The total taxa of the naturalized plant communities consisted of 31 families, 86 genera, 114 species and 13 varieties. Of which the taxa of the naturalized plant species consisted of 8 families, 21 genera, 25 species and 1 variety. The result of Bray-Curtis ordination revealed that the plots suveyed were arranged according largely to the vegetation units of' the communities. Also the interspecific affinity was examined by an analysis of interspecific association and the main component species in the communities were divided into two groups. The naturalized rate was higher in the communitise affected by strong human impacts, while was lower in the communities affected relatively less by human impacts. On the other hand the seasonal changes of the communities and the naturalized rate between the spring and the autumn were investigated. Many naturalized communities present in Spring were replaced by the other native ruderal communitues in the Autumn. The naturalized rate based on the dominance was largely decreased over from the spring to the Autumn.

Based on the list of the rare plants by the Forest Research Institute, 2 taxa were recorded in the studied areas; Lilium distichum (Presevation priority order: No. 159), Aristolochia contorta (No. 151) and based on the list of Korean endemic plants, 4 taxa were recorded; Cephalotaxus koreana, Carex okamotoi, Salix purpurea var. japonica, Weigela subsessilis. Specific plant species by floral region were total 21 taxa; 2 taxa (Asperula lasiantha, Lonicera subhispida) in class III, 4 taxa (Lilium distichum, Potentilla dickinsii, Caryopteris incana, Ligularia fischeri) in class II, 15 taxa (Hosta capitata, Alnus hirsuta, Ribes mandshuricum, Cayratia japonica, Vaccinium oldhami, etc.) in class I. The naturalized plants in this site were 12 families, 28 genera, 31 species, 1 varieties, 32 taxa and naturalization rate was 9.8%. So, wild plants disturbing ecosystem like Ambrosia artemisiifolia var. elatior have been increasing and it needs continuing control and conservation measures on the plant ecosystem.
