Abstract
논둑에 분포하고 있는 식생구조에 대해 식물사회학적 연구를 수행하였다. 총59개 조사구에 대한 식생자료의 분석은 Zurich-Montpellier 학파의 방법을 이용하였다. 논둑 식생조사 결과3군단, 3군집, 3군락으로 구분되었다: 쑥-수크령군단(바랭이-돌피군집, 쑥-개망초군락, 띠군락, 한삼덩굴-돌콩군락), 참억새-새군단(억새군집), 미국가막사리-개기장군단(고마리군집). DCA분석에서 식생단위와 환경과의 상관관계를 보면, 쑥-개망초군락과 띠군락은 토양 경도와 양의 상관관계, 습한 논둑에 서식하는 고마리군집과 서식폭이 넓은 억새군집은 전질소와 높은 상관관계를 나타내었다. The phytosociological study was carried out to investigate the structural characteristics of paddy levee vegetation in South Korea. The vegetation data of total 59 releves were analyzed by the Zurich-Montpellier school's method. 6 syntaxa (3 associations and 3 communities) of paddy levee were recognized : Echinochlo-Digitaretum ciliaris ass. nov. hoc., Artemisia princeps-Erigeron annus community, Imperata cylindrica v. koenigii community, Glycine soja-Humulus scandens community, Miscantheum sinensis f. purpurascens ass. nov. hoc,, Polygonetum thunbergii Lohm. et Miyawaki 1962. Detrended correspondence analysis(DCA) showed that Artemisia princeps-Erigeron annus community and Imperata cylindrica v. koenigii community were positively correlated with soil hardness. Polygonetum thunbergii Lohm. et association and Miscantheum sinensis f. purpurascens ass. nov. hoc. was intimately correlated with high soil total nitrogen.
