We surveyed the distribution of exotic weeds in the 350 upland crop fields of Gyeonggi-do. The exotic weeds were summarized as 78 taxa including 19 families, 52 genera, 74 species and 4 varieties. Among the total exotic weeds, the summer annuals were 48.7%, the winter annuals 28.2%, and the perennials 23.1%. Compositae was dominant family (32%), followed by Gramineae (8%), Polygonaceae (8%) and Malvaceae (7%). Dominant exotic weeds in northern Gyeonggi-do were Amaranthus lividus, Ambrosia trifida, Chenopodium album, Bidens frondosa and Erigeron Canadensis, and in southern Gyeonggi-do were Chenopodium album, Erigeron Canadensis, Erigeron annuus, Taraxacum officinale and Galinsoga ciliate. The most dominant exotic weeds in the Gyeonggi-do were Chenopodium album, followed by Amaranthus blitum, Erigeron canadensis. Canonical correspondence analysis for investigation of correlation between exotic weeds occurred in northern and southern Gyeonggi-do showed that the exotic weeds in northern Gyeonggi-do were more diverse then in southern Gyeonggi-do. This information could be useful for establishment of exotic weed control methods in Gyeonggi-do.

경기도밭의외래잡초분포 285 다 (Oh et al., 2002). 국내도서지역중백령도, 흑산도, 추자도, 거문도에발생하는외래잡초는 18과 70종으로이중일년생이 40%, 월년생이 30% 를차지하는것으로알려져있다 (Kim et al., 2010). 경기, 강원및제주의농경지에서발생하는외래잡초를포괄적으로조사한결과에서는 19과 79종으로확인되었다 (Oh et al., 2004). 본연구는경기도지역의밭경작지를대상으로외래잡초의분포및발생피도등급을조사하여밭에발생하는외래잡초의종류와특징을밝혀내고외래잡초의관리를위한기초자료를구축하기위하여수행하였다. 재료및방법 외래잡초분포조사외래잡초의분포조사는 2014년 5월부터 9월까지경기도의북부와남부지역을대상으로실시하였다. 경기북부지역은가평군, 고양시, 김포시, 남양주시, 양주시, 연천군, 파주시, 동두천시, 포천시등 9개시군을, 경기남부지역의과천시, 광명시, 광주시, 군포시, 남양주시, 부천시, 성남시, 수원시, 시흥시, 안산시, 안성시, 안양시, 양평군, 여주시, 오산시, 용인시, 의왕시, 이천시, 평택시, 하남시, 화성시 21개시군을대상으로하였다. 총 350필지를대상으로하였으며, 이가운데경기북부는 157필지, 경기남부는 193필지를조사하였다. 외래잡초분포조사지점은밭위치를위성으로파악하여시군의밭이고루조사될수있도록선정하였고조사구의면적은 1필지를대상으로하여측정하였다. 식물의피도는 Braun Blanquet (1964) 의방법으로 7개등급 (r, +, 1, 2, 3, 4, 5) 을기준으로조사하였다. 위하여 Canonical correspondence analysis (CCA) 을수행하여생태학적관점에서지역과종과의상호관계를분석하였다 (Ter Braak, 1986). 결과및고찰 발생외래잡초경기남 북부 350개의밭에발생하는외래잡초는 19과 51속 72종 6변종, 총 78분류군이출현하는것으로조사되었다. 이는 Oh et al. (2004) 의연구에서경기도에 52종류가보고된 2004년에비해많은종이경기도밭에분포하고있는것을확인할수있었다. 이중경기북부는 18과 43 속 59종 2변종, 총 61분류군, 경기남부는 15과 36속 47종 3 변종, 총 50분류군이분포하는것으로나타났다. 출현한외래잡초총 78종의생활형은경기북부가일년생 47.5%, 월년생 31.1%, 다년생 21.3% 로구성되었고경기남부는일년생 56.0%, 월년생 28.0%, 다년생 16.0% 가출현하였다. 경기도전체의외래잡초생활형은일년생이 48.7%, 월년생 28.2%, 다년생 23.1% 로다년생보다는일년생과월년생의비율이높았다 (Table 1). 경기도밭에출현한외래잡초중생태계교란생물은가시박, 가시상추, 돼지풀, 단풍잎돼지풀, 도깨비가지, 미국쑥부쟁이, 서양등골나물, 애기수영 8종이출현하였다. 외래잡초의과별비율은국화과 32%, 벼과 8%, 마디풀과 8%, 아욱과 7%, 십자화과 6%, 메꽃과 6%, 현삼과 5%, 비름과 5%, 가지과 5%, 명아주과 4% 등으로구성되었다 (Fig. 1) 밭외래잡초의과별분포비율을조사한 Park et al. (2003) 에따르면, 국화과가우점하였는데, 본연구에서도이러한경향은일치하였다. 발생외래잡초및분포특성분석외래잡초조사결과는국가표준식물목록 (KNA, 2007) 및한국의귀화식물원색도감 (Park, 2009) 을참고하였다. 출현한외래잡초종에대해서는 Raunkiaer (1934) 의생활형을기준으로일년생과다년생을구분하였고과별분포비율을산정하였다. 외래잡초의우점순위를알아보기위하여중요치 (IV) 분석을실시하였다 (Curtes and Mc Intosh, 1950).
