Abstract

The phytosociological study was carried out to investigate the structural characteristics of fallow paddy vegetation in Korea. The vegetation data of total 22 relev$\'{e}$s were analyzed by the Zurich-Montpellier school's method. Six syntaxa (1 subassociations and 5 communities) of fallow paddy were recognized: Polygonetosum thunbergii typicum subass. nov. hoc., Aneilema keisak community, Juncus effusus var. decipiens community, Phragmites commuis community, Monochoria vaginalis var. plantaginea community, Typha orientalis community of Polygonetum thunbergii Lohm. et Miyawaki 1962. Detrended correspondence analysis showed that Aneilema keisak community and Monochoria vaginalis var. plantaginea community were negatively correlated with soil total nitrogen. Polygonetosum thunbergii typicum subass. nov. hoc. and Phragmites commuis community was distributed in the soil with low pH.

휴경논에 분포하고 있는 식생구조에 대해 식물사회학적 연구를 수행하였다. 총 22개 조사구에 대한 식생자료의 분석은 Zurich-Montpellier 학파의 방법을 이용하였다. 휴경논 식생조사 결과 1아군집, 5군락으로 구분되었다. 고마리군집(Polygonetum thunbergii Lohm. et Miyawaki 1962)의 고마리전형아군집, 골풀군락, 갈대군락, 물달개비군락, 사마귀풀군락, 부들군락. 요인분석에서 식생단위와 환경과의 상관관계를 보면, 사마귀풀군락과 물달개비군락은 토양 전질소와 음의 상관관계, 갈대군락과 고마리아군집은 토양 pH가 낮은 지역에 분포하는 것으로 분석되었다.
