Abstract

This study was carried out to investigate the distribution status and urbanization index of the naturalized plants. For this purpose, 7 cities and counties in the eastern area of Jeollanamdo were selected and investigations were conducted on a total of 14 sites, during the period of March 2006 to November 2008. The naturalized plants were identified as 123; 22 families, 75 genera, 118 species, and 5 varieties. As for the urbanization index, Suncheon city had the highest level of urbanization (33.45%) and Gurye county the lowest level of urbanization (20.21%). Classification families were as follows: Compositae 40 kinds (30.1%) Gramineae 17 kinds (12.8%) and Leguminosae 14 kinds (10.5%). Major communities of naturalized plants consisted of 20 communities including Erigeron annuus community, Erigeron canadensis community, Alnus firma community, Amorpha fruticosa community, Oenothera odorata community, Bidens frondosa community, Coreopsis tinctoria community, Ambrosia artemisiifolia var. elatior community etc. Invasive naturalized plants consisted of 5 taxa: Ambrosia artemisiifolia var. elatior, Ambrosia trifida, Eupatorium rugosum, Paspalum distichum var. indutum and Paspalum distichum. The distributional characteristics of naturalized plants were divided on the basis of six areas associated with ecological characteristics of a habitat.

본 조사는 2006년 3월부터 2008년 11월까지 전라남도 동부지역 7개 시 군 14개 지역의 귀화식물과 도시화지수를 분석하였다. 귀화식물은 총 22과 75속 118종 5변종 123종류가 조사되었다. 조사지역별로는 순천시 시가지가 83종으로 가장 많았고, 여수시 산업단지 66종, 여수시 시가지와 고흥군 도로변이 각각 52종이었다. 낮게 나타난 지역은 순천시 쓰레기매립장과 장흥군 농공단지가 각각 21종, 구례군 지리산국립공원 구례지역이 27종이었다. 도시화지수는 순천시가 30.31%로 가장 높았고, 구례군이 18.12%로 가장 낮았다. 과별 출현 종류는 국화과 37종류(30.1%)로 가장 많았고, 벼과 17종(13.8%), 콩과 14종(11.4%), 십자화과 8종(6.5%), 마디풀과 7종(5.7%), 메꽃과 5종(4.1%) 순이었다. 주요 귀화식물군락은 아까시나무군락, 족제비싸리군락, 원추천인국군락, 털물참새피군락, 서양민들레군락, 미국자리 공군락, 양미역취군락, 소리쟁이군락, 개망초군락, 망초군락, 달맞이꽃군락, 미국가막사리군락, 기생초군락, 돼지풀군락, 만수국아재비군락, 울산도깨비바늘군락, 노랑코스모스군락, 애기땅빈대군락, 미국개기장군락, 비짜루국화군락 등 총 20개 군락이 확인되었다. 생태계 위해 귀화식물은 돼지풀, 단풍잎돼지풀, 서양등골나물, 털물참새피, 물참새피 등 5종이었다. 생육지별 특성에 따라 시 군 읍 지역, 국립공원지역, 농공단지 지역, 강 및 하천지역, 쓰레기매립장 지역, 항만 및 산업단지 지역 등 6개 지역으로 구분하였으며, 각 분포지역의 생태적 특성을 비교한 후 관리방안을 제시하였다.
