Abstract

This study aimed to provide basic data for efficient flora management of vascular plants, halophytes, and naturalized plants in the Gwangpo Bay area in Sacheon city, Gyeongsangnam-do. The flora found in this area incorporated 520 taxa, including 93 families, 299 genera, 466 species, 3 subspecies, 41 varieties, and 10 forma, and accounted for approximately 10.6% of total vascular plants (4,884 species) in Korea. According to the survey, 76 species of Gramineae showed the highest frequency (14.6%), followed by 67 species of Compositae (12.8%), 34 species of Leguminosae (6.5%), 27 species of Cyperaceae (5.2%), and 22 species of Rosaceae (4.2%). Rare plant species designated by the Korea Forest Service were categorized into six taxa, including three taxa in the LC grade, one taxon in the CR grade, one taxon in the VU grade, and one taxon in the EN grade. Korea endemic plants belonged to nine taxa consisting of seven families, seven genera, and nine species. The special floristic plants included 44 taxa, including one taxon (Prunus yedoensis) in the V grade, four taxa in the IV grade, ten taxa in the III grade, six taxa in the II grade, and 23 taxa in the I grade. Naturalized plants included 62 taxa consisting of 15 families, 47 genera, 59 species and 3 varieties. Halophytes consisted of 27 taxa, including 13 families, 24 genera, 24 species, 2 varieties, 1 forma, which consisted of Atriplex gmelinii, Suaeda glauca, Suaeda maritima, and Lathyrus japonicus. Invasive alien species in the Gwangpo Bay area included seven taxa. Since Ambrosia artemisiifolia, Sicyos angulatus, andPaspalum distichum var. indutummay have harmful effects on native plants, these plants must be artificially controlled.

본 연구는 생태적·경관적 가치가 뛰어난 광포만의 관속식물, 염생식물, 침입외래식물의 분포에 관한 연구를 통해 이 지역의 식물자원을 체계적으로 관리하는 방안을 수립하는데 필요한 기초자료 제공이 목적이다. 광포만에서 출현한 관속식물은 93과 299속 466종 3아종 41변종 10품종으로 520종이었다. 산림청 지정 희귀식물중 LC등급은 검팽나무, 새박, 모새달 등의 3분류군, VU등급은 세뿔석위 1분류군, CR등급은 왕벚나무 1분류군, EN등급은 왕둥굴레가 출현하였다. 한국 특산식물은 해변싸리, 오동나무, 병꽃나무 등의 9분류군이 출현하였다. 식물구계학적 특정식물은 44분류군으로 V등급은 왕벚나무 1분류군, IV등급은 산복사나무, 등나무, 검양옻나무, 갈사초 등의 4분류군, III등급은 바위손, 세뿔석위, 참조팝나무 등의 10분류군, II등급은 방기, 개산초, 새박 등 6분류군, I등급은 실고사리, 잣나무, 가래나무 등 23분류군이 출현하였다. 침입외래식물은 돼지풀, 가시박, 털물참새피 등 62분류군이 출현하였다. 염생식물은 갯장구채, 나문재, 해홍나물 등 27분류군이 출현하였다. 생태계교란종은 7분류군이 출현하였으며 특히, 돼지풀, 가시박, 털물참새피 등은 자생식물의 생육환경에 악영향을 미칠 수 있어 인위적인 방제가 반드시 수반되어야 할 것이다.
