Abstract BACKGROUND: The field margins, which are uncultivated area of permanent vegetation located adjacent to field, play an important role in enhancing biodiversity in the agricultural ecosystem. This study focused on floristic characteristics on dry field margins in Korea Peninsula. METHODS AND RESULTS: This study was conducted at margins of 196 dry fields in 32 areas in 8 provinces in May and September 2013. The vascular plants of the dry field margins were listed 347 which contain 73 families, 219 genera, 311 species, 1 subspecies, 30 varieties and 5 forms. Of these 347, 48 were woody plants and 299 were herbaceous plants. Among total 73 families, Compositae (17.6%) was the most dominant family, and followed Gramineae (15.9%), Polygonaceae (5.8%), Leguminosae (4.9%) and Cyperaceae (3.8%). Based on relative frequency values of survey fields, the appearance *Corresponding author: Young-Eun Na Phone: +82 63 238 0756; Fax: +82 63 238 3823; E-mail: youngman99@korea.kr frequency of Digitaria ciliaris (89.8%) was the highest, and followed Acalypha australis (86.2%), Artemisia princeps (82.1%), Commelina communis (80.6%) and Portulaca oleracea (80.6%). Disturbance index of dry field margins was 55.0% at national level, and Gangwon region was the highest among the 8 regions at regional level. Life form spectrum was determined to be Th-R 5 -D 4 -etype. CONCLUSION: These results will be used fundamental data for studies to improve or even stabilize the current state of plant biodiversity in agricultural environments.

Location of survey sites. 1997). 잡초와작물은경쟁관계에있으며잡초의발생과작물의수량과는밀접한관계를가지고있어국내에서는잡초의효과적인방제및관리를위한조사연구가주로수행되어져왔다 (Kim, 1970; Park et al., 2003; Lee et al., 2007). 국외에서는경작지주변부에서식하는식물이작물의생육에영향을미치는생태적기능에대한관심이늘어나고있으며 (Van Emden, 1990; Wiens, 1992; Bennet et al., 1994; Boatman 1994; Halley et al., 1996) 방풍 (Forman and Baudry, 1984), 침식방지 (Tim and Jolly, 1994), 천적과화분매개체의양적증가 (Banaszak, 1983, 1992) 에기여하는것으로보고되고있다. 또한이러한경작지주변부는동 식물의먹이원, 서식처및월동처등의다양한기능을수행하고있다 (Potts, 1986; Kaule and Krebs 1989; Bunce et al., 1994; Tew et al., 1994; Marshall and Moonen 2002). 그러나최근수십년동안경작지주변부의식물다양성은크게감소하고있으며 (David and Marein, 2000), 이로인해농업시스템에서제공되는생태계서비스기능 ( 미세기후조절, 수문과정, 해충제어, 유해물질제거등 ) 이축소되고있다 (Altieri, 1999). 국내에서는잡초방제를위한재배작물별현황조사 (Kim, et al., 1987; Kim, 1998; No et al., 2004; Choi et al., 2009, Lee et al., 2014a, 2014b) 와식물에서분비되는천연물을제초제로활용하기위한연구 (Shim et al., 1991; Chon and Kim, 2005) 가수행되고있지만생태적측면에서의식물다양성에대한연구는수행되고있지않다. 국내경작지에대한생태학적연구는논, 밭에분포하는식물군락에대한군락분류및군락생태 (Song, 1997; Kim and Nam, 1998; Lee, 1999; Oh et al., 2008), 전라도의밭경작지에분포하는식물상의생태적특성 (Cho et al., 2014), 농경지유형별 C4식물의분포양상등에관한연구 (Cho et al., 2013) 가수행되어있다. 본연구는국내밭경작지주변부에서식하는식물의다양성을확인하고생태적특성을밝혀향후국내경작지생태계의기능적연구와인위적인관리로인해나타나는식물상변화예측및농경지생물다양성증진을위한기초자료를제공하고자수행하였다. 재료및방법 식물조사조사지역은경기도 ( 남양주시, 이천시, 파주시, 화성시 ), 강원도 ( 춘천시, 홍천군, 원주시, 평창군 ), 충청북도 ( 괴산군, 옥천군, 청원군, 충주시 ), 충청남도 ( 공주시, 논산시, 당진시, 홍성군 ), 전라북도 ( 고창군, 김제시, 임실군, 정읍시 ), 전라남도 ( 영광군, 영암군, 진도군, 해남군 ), 경상북도 ( 문경시, 김천시, 칠곡군, 안동시 ), 경상남도 ( 창녕군, 함안군, 김해시, 밀양시 ) 에분포하고있는밭경작지의주변부를대상으로하였다 (Fig. 1). 각도별 4지역을대상으로총 32개시 군에서 196 밭필지의주변부에서식하는식물종이조사되었다. 각지역의조사지는밭경작지의특성을나타낼수있도록최소한 5필지가연속적으로연결된곳을임의로선정하였다. 식물상조사는 2013년 5월및 9월에 2차례수행하였으며, 밭필지와접하고있는밭둑과밭둑경사면을조사범위로설정

Characteristics of Flora on Dry Field Margins in Korean Peninsula 79 하여조사하였다 (Cho et al., 2014). 조사지역에서미동정된식물은채집하여실험실에서식물도감 (Lee, 1996a; Lee, 2003; Park, 2009) 을이용하여동정하였고식물명은국가표준식물목록 (Korea National Arboretum and The Plant Taxonomic Society of Korea, 2007) 을기준으로하였다. 또한각도별식물종의출현빈도는상대빈도 (n i/n 100, 여기서 n i 는 i종이출현한조사지점수이며 N은전체조사지점수 ) 를통하여나타냈다. 생활형분석조사된식물의생태적특성을확인하고자생활형 (life form) 을분석하였다. 생활형은 Raunkiaer(1934) 와 Numata (1969) 의방법으로국내식물종에적용하여 Lee(1996b) 가제시한휴면형, 번식형 ( 지하기관형, 산포기관형 ), 생육형으로구분하여정리하였다. 그리고휴면형을이용한교란지수 (Di; Disturbance index, Benabdelmoumence et al., 2014) 를산출하였다. 교란지수는서식처의안정성에대한상대적평가를가능하게하는값으로서높을수록서식처가불안정하다는것을의미한다. 교란지수의산출방법은 (Ch i+th i)/s i 100으로 Ch i 는 i지역의지표식물 (Chamaephyte) 종수이고 Th i 는 i지역의일년생식물 (Therophyte) 종수이며 S i 는 i지역의전체출현식물종수이다.

Kim et al.(1992) 은전국밭잡초조사에서바랭이, 쇠비름, 깨풀, 강아지풀, 방동사니등을우점종으로기재하고있으며, Cho et al.(2013) 은쑥, 개망초, 한삼덩굴, 망초, 명아주, 바랭이, 닭의장풀등이고빈도로출현한다고하였다. 또한 Choi et al.(2009) 은충남북지역의잡초발생연구에서바랭이, 깨풀, 주름잎, 참방동사니, 개망초, 쇠비름, 중대가리풀, 뽀리뱅이등의순으로출현빈도가높게나타난다고보고하였다. 본연구가밭경작지주변부를대상으로조사지역을한정한것을고려했을때출현빈도의순위는다소차이가있
