Abstract

This study was carried out to investigate the distribution status and UI(urbanization index) of the naturalized plants and exotic plants. For this purpose 7 cities and counties in the northern South Jeolla Province were selected and investigations were conducted on a total of 14 sites, two sites from each city or county, during the period of March to November 2006. The exotic plants were identified as 111 taxa; 26 families, 79 genera, 105 species, and 6 varieties. As for urbanization index, Hampyeong County had the highest level of urbanization(21.95%) and Gokseong County the lowest level of urbanization(16.38%). Naturalized plants classified as family were as follows: Compositae was 36 kinds(32.43%) Graminae 17 kinds(15.31%) and Leguminosae 7 kinds(6.31%). Major communities of naturalized plants consisted of 21 communities including Robinia pseudoacacia-Amorpha fruticosa community, Erigeron annuus community, Erigeron canadensis community etc. Invasive naturalized plants consisted of 7 taxa: Paspalum disticum var. indutum, Paspalum distichum, Rumex acetocella, Solanum carolinense, Aster pilosus, Ambrosia artemisiifolia var. elatior and Ambrosia trifida. The study shows that the integrated management of exotic plants on a national scale is needed. It also recommend that a systematic and integrated management of exotic plants in the northern South Jeolla Province is crucial to preserve and protect natural species.

본 논문은 2006년 3월부터 11월까지 전라남도 북부지역 7개 시 군 지역에서 각 2곳을 선택하여 총 14개 조사 지역에서 외래식물과 귀화식물의 도시화지수를 분석하였다. 귀화식물은 26과 79속 105종 6변종 111종류로 확인되었다. 도시화지수는 함평군이 21.95%로 가장 높았으며 곡성군이 16.38%로 가장 낮았다. 귀화식물 과별 출현종류는 국화과가 36종류(32.43%)로 가장 많았고, 벼과 17종류(15.31%), 콩과 7종류(6.31%) 순이었다. 주요 귀화식물군락은 군락조성표에 따라서 아까시나무와 족제비싸리군락, 개망초군락 및 망초군락 등 21개 군락이 확인 되었다. 생태계 위해귀화식물은 털물참새피, 물참새피, 애기수영, 도깨비가지, 미국쑥부쟁이, 돼지풀 및 단풍잎돼지풀 등 7종이었다. 국가 차원에서 외래종의 통합관리방안이 필요하지만 외래종분포를 확인하여 지속적인 관리를 하는 것이 자생종의 보전과 보호에 있어서 매우 중요한 역할을 하게 될 것이다.
