This study was conducted in order to investigate the distribution pattern of weeds on upland crop field in northern Gyeonggi-do. The weeds were summarized as 201 taxa including 42 families, 129 genera, 178 species, 1 subspecies, 21 varieties and 1 form. One hundred and thirty one species were classified to annual plants, accounting for 65.1% and 70 species were classified to perennials, accounting for the rest of 34.9%. Compositae was dominant family (21%), followed by Gramineae (12%), Polygonaceae (7%) and Brassicaceae (5%). Among the weeds appearing in the fields of northern Gyeonggi-do, the invasive weeds were classified to 62 species in18 families. The most dominant weed species in the fields were Portulaca oleracea, followed by Echinochloa crus-galli, Amaranthus lividus. Detrended correspondence analysis for investigation of occurrence pattern of weeds by crops revealed the occurrence pattern of weed species in adlay field were different from those in other crop fields. This information could be useful for establishment of weed control methods in northern Gyeonggi-do.

경기북부밭잡초분포 277 밭에발생하는잡초는 29과 102종이분포하고바랭이, 쇠비름, 방동사니등이우점종으로출현하였다 (Lim et al., 2008). 충청남북도지역의밭에서는 36과 124종이분포하는것으로알려져있다 (Choi et al., 2009). 밭은인간의간섭과관리가지속적으로이루어지는입지환경으로교란된환경속에서도균질성을지닌잡초군락을형성하고이러한잡초군락은입지의미세환경조건을반영하고있다 (Kim, 2004). 따라서본연구는경기북부지역밭을대상으로잡초의분포및발생피도등급을조사하여밭에발생하는잡초의종류와특징을밝혀내고문제잡초의향후변화양상에대비하고자수행하였다. 재료및방법 조사지역경기북부지역의가평군, 고양시, 김포시, 남양주시, 양주시, 연천군, 파주시, 포천시 8개시, 군에대하여현지조사를실시하였고현지조사는 2014년 5월부터 9월까지 143필지를선정하여진행하였다 (Fig. 1). 잡초분포조사잡초분포조사는경기북부 8개시, 군의밭위치를위성으로파악하여시군의밭이고루조사될수있도록선정하였고조사구의면적은 1필지를대상으로하여식물의피도를측정하였다. 식물의피도는 Braun-Blanquet (1964) 의방법으로 7개등급 (r, +, 1, 2, 3, 4, 5) 을기준으로조사하였고피도조사시식물층간높이를고려하여작은키의잡초 ( 초본 2층 ), 큰키의잡초 ( 초본 1층 ) 의피도가모두기록될수있도록하였다. 잡초분석잡초조사결과는국가표준식물목록 (KNA, 2014) 에의거하여목록을작성하였고외래잡초는한국의귀화식물원색도감 (Park, 2009) 에의해표기하였다. 출현한잡초종에대 Fig. 1.
