Abstract

This study was carried out to illuminate the flora of vascular plants of islands at Chungnam. This study was conducted from March to November, 2010. Based on the voucher, vascular plants of in investigated islands were 105 families 326 genera 454 species 4 subspecies 45 varieties 9 forms, totally 512 taxa. Korean endemic plants were 6 species such as Aster koraiensis, Salix koriyanagi, Indigofera koreana, Hemerocallis taeanensis, Hepatica insularis, Philadelphus schrenckii, rare and endangered plants of designated by Korea Forest Service were 4 taxa, such as Magnolia kobus (planted), Koelreuteria paniculata, Berchemia racemosa var. magna, Glehnia littoralis respectively. Phytogeographical special plants were totally 69 taxa, which were grade I of 50 taxa, grade II of 1 axon, grade III of 11 taxa, grade IV of 4 taxa, and grade V of 3 taxa. 14 southern plants and 4 northern plant by criterion from climate change study were found in this area. Naturalized plants were 17 families 46 taxa, that was 9.1% of total vascular plants in this area. Even naturalized plants has not influence on the islands vegetation. However, regular passenger ferry between islands and increasing of visiter will be affecting vegetation.

본 조사는 당진, 서산, 태안, 홍성, 보령, 서천 등 충남 도서지역의 관속식물 분포를 연구하기 위해 2010년 3월부터 11월까지 조사하였으며, 본 조사를 통해 확인된 조사지역 내의 소산 관속식물은 105과 326속 454종 4아종 45변종 9품종으로 총 512분류군으로 확인되었다. 조사지역내의 한국특산식물은 벌개미취, 키버들, 좀땅비싸리, 태안원추리, 새끼노루귀, 고광나무 등 총 6분류군으로 확인되었으며, 산림청지정 희귀 및 멸종위기 식물은 목련, 모감주나무, 먹넌출, 갯방풍 등 총 4분류군이 확인되었다. 식물구계학적 특정종은 I등급종은 50분류군, II등급종은 1분류군, III등급종은 11분류군, IV등급종은 4분류군, V등급종은 3분류군으로 총 69분류군이 확인되었다. 기후변화와 관련한 연구 결과에 의한 기준으로 보면 남방계가 14분류군, 북방계가 4분류군이 확인되었다. 귀화식물은 17과 46분류군으로 확인되었으며, 이는 조사된 전체 소산 식물목록 중 약 9.1%를 차지하고 있었다. 귀화식물은 군락을 형성하지 않은 상태로 주변 도서지역의 식생에 큰 영향을 주지 못하는 것으로 확인되었다. 하지만, 도서지역 간에 정기적으로 여객선이 오가며 관광객이 증가함에 따라 종수가 증가하고, 주변 도서지역에 많은 영향을 미칠 것으로 사료된다.
