Abstract

This research aimed to identify the diversity and the distribution of invasive alien plant species in the metropolitan city of Busan, South Korea. According to our results, we discovered 10 species of invasive alien plants distributed in Busan, demonstrating that this urban area has a high domestic plant diversity. A cluster analysis identified that the dominant communities of Aster pilosus, Lactuca serriola, Ambrosia artemisiifolia, Rumex acetosella and Solanum carolinense were highly similar in species composition. Different species of invasive alien plants tended to occur together in dominant communities, indicating their preference for shared habitats. The most extensively distributed species in Busan were Lactuca serriola (16 districts), followed by Ambrosia artemisiifolia (11 districts), Aster pilosus (11 districts) and Rumex acetosella (10 districts). The administrative districts with the most diverse invasive alien plants were Gangseo-gu (8 species) and Buk-gu (8 species), which are both areas with high human interference and diverse habitats. Additional environmental information was collected for these species' habitats in Busan. The results of this research can be used to assess the current status of invasive alien plants in Busan and can provide basic data useful for effectively controlling and preventing the spread of invasive plants.

부산광역시에 분포하는 생태계교란식물에 대해 종 다양성과 분포현황을 규명하고자 연구를 수행하였다. 연구 결과 부산광역시에는 10종의 생태계교란식물이 분포하고 있는 것으로 확인되었으며, 국내에서 높은 종 다양성을 보이는 지역으로 확인되었다. 집괴분석을 통해 미국쑥부쟁이 우점군락, 가시상추 우점군락, 돼지풀 우점군락, 애기수영 우점군락, 도깨비가지 우점군락 등이 높은 유사성을 나타내는 것으로 확인되었다. 생태계 교란식물은 우점군락 내에서 다른 생태계 교란식물이 함께 혼생하는 경향을 보여, 유사한 서식처를 공유하고 있는 것올 밝혀졌다. 부산시에서 가장 광범위한 분포경향을 보이는 종은 가시상추(16개 구)이며, 돼지풀(11개 구), 미국쑥부쟁이(11개 구), 애기수영(10개 구) 등이 넓은 분포를 보였다. 행정구역 중 가장 다양한 생태계교란식물이 출현한 지역은 강서구(8종)와 북구(8종)이며, 인위적 간섭이 높으면서 다양한 서식처가 존재하는 지역들로 확인되었다. 부산광역시의 종별 서식처 환경정보가 수집되었다. 본 연구를 통한 결과는 부산광역시 내 생태계교란식물의 현황파악과 더불어 효율적 관리와 확산 방지를 위한 기초자료로 활용될 수 있을 것으로 기대된다.
