한반도 해안염습지와 사구 염생식물 분포 = Distribution of halophytes in coastal salt marsh and on sand dunes in Korea

다국어 초록 (Multilingual Abstract)

To elucidate the distribution of halophytes in Korea, we surveyed 95 coastal salt marsh and sand
dune areas. As a result, 62 halophytes of 57 species, 4 varieties and 1 form belonging to 44 genera and 21 families
were recorded from coastal regions and islands of South Korea. Of these, 33 taxa were plants growing on sand
dunes and the other 29 in salt marsh. Fifty eight taxa were found on the west coast, which was surveyed at 61
areas. The most common species among them were Suaeda glauca (Bunge) Bunge, Suaeda japonica Makino,
Phragmites communis Trin., Zoysia sinica Hance, Carex scabrifolia Steud. in salt marsh, and Salsola komarrovii
Iljin, Lathyrus japonicus Willd., Limonium tetragonum (Thunb.) A.A. Bulloc, Calystegia soldanella Roem. &
Schult. on sand dunes. On the other hand, only 45 taxa were found on the southern coast, surveyed at 15 areas.
On the east coast, surveyed at 13 areas, 44 taxa were found. The most common species were Salsola komarrovii
Iljin, Lathyrus japonicus Willd., Calystegia soldanella Roem. & Schult., on sand dunes and Linaria japonica
Miq., which on the Korean peninsula is found only on the east coast. On Jeju Island, surveyed at 6 areas, 30 taxa
of halophytes were found. Canavalia lineata (Thunb.) DC. is found in Korea only on Jeju Island. About half of
the Korean halophytes were members of three families (Chenopodiaceae: 12 species, Poaceae: 12 species and
Asteraceae: 7 species).

국문 초록 (Abstract)

본 연구는 한반도산 염생식물 분포를 밝히기 위해 해안 염습지와 사구 95지역을 조사하였다. 연구결과 남한의 해안과 섬지역 등에서 21과 44속 57종 4변종 1품종 등 62 염생식물이 기록되었다. 이 중 33분류군은 사구에 자라며, 나머지 29분류군은 염습지에 자라는 식물이다. 61지역이 조사된 서해안에는 58분류군이 분포하였으며, 이들 중 염습지에서는 나문재, 칠면초, 갈대, 갯잔디, 천일사초가, 사구에서는 수송나물, 갯완두, 갯길경, 갯메꽃이 많이 발견되었다. 한편 15지역이 조사된 남해안에는 서해안 보다 적은 45분류군이 분포하였다. 13지역이 조사된 동해안에는 44분류군이 분포하였으며, 흔히 발견된 식물은 수송나물, 갯완두, 갯메꽃으로 모두 사구식물이다. 해란초는 한반도에서는 동해안에서만 조사되었다. 6 지역이 조사된 제주도에는 30분류군이 분포하였다. 해녀콩은 국내에서는 제주도에서만 발견되었다. 한국산 염생식물 중 약 절반은 12종의 명아주과, 12종의 벼과, 7종의 국화과 등 3과에 속하였다.
