Abstract

BACKGROUND: As a result of rural exodus, aging of rural population, development of high-yield rice varieties and so on, abandoned paddy fields of South Korea have generally increased. The phytosociological studies are needed to recommend the effective vegetation management methods of abandoned paddy fields. The current study performed an analysis of vegetation characteristics by classifying plant communities for abandoned paddy fields in South Korea. METHODS AND RESULTS: A comparative analysis of syntaxonomy, synecology, and syndynamics was performed by using the Z.-M. method of phytosociology and vegetation survey which was obtained from an enumeration district of total 203 phytosociological releves of 5 regions in Gangwon-do, 5 regions in Gyeonggi-do, 2 regions in Chungcheong-do, 18 regions in Gyeongsang-do, and 10 regions in Jeolla-do. Alopecurus aequalis community, Juncus effusus var. decipiens community and Salix koreensis community were, respectively, identified as successional plant communities of the early stage, the middle stage, and the late stage in the vegetation of abandoned paddy field. Sere of abandoned paddy field can be classified, developmentally, into annual plant stage, perennial plant stage, shrub plant stage, and forest tree stage. Several kinds of dominant species rather than a distinct species were found in the middle stage of abandoned paddy field. CONCLUSION(S): In this study, changing pattern in vegetational communities of abandoned paddy field were understood. These results will provide important information for restoring and conserving the ecology of fallow ground.

농촌인구의 감소와 잉여생산작물로 변화된 쌀의 수요에 대비해 최근 20-30년간 휴경논, 즉 묵논이 증가하여 왔으나, 새로운 작물재배지로의 전환 또는 용도지역 변경으로 인한 형질변경이 수반되지 않는 오지의 묵논은 점차 식물생태복원의 주요한 입지로 새롭게 부각되고 있다. 묵논의 입지적, 수리적 여건상 묵밭에 비해 식물의 천이가 활발하고, 습지로서의 기능과 다양한 생물 서식지로서의 기능 등 생태적으로 긍정적인 역할을 담당하게 될 묵논은 연차별로 식물군락의 변화양상이 달라진다. 본 연구에서는 우리나라 전역에 분포하는 묵논을 대상으로 초기, 중기, 후기묵논으로 구분짓고, 각 시기별 식물군락의 변화양상에 대한 식물사회학적 연구가 수행되었다. 강원 경기 5개 권역, 충청남 북 2개 권역, 경상남 북 18개 권역, 전라남 북 10개 권역 등 총 35개 권역을 대상으로 총 203개소의 조사구에서 획득한 식생조사표를 이용하여 군락분류, 군락생태, 군락동태에 대한 비교분석이 이루어졌다. 본 연구를 통해 우리나라 초기, 중기, 후기의 천이단계별 식물군락은 각각 뚝새풀군락, 골풀군락, 버드나무군락으로 특징지어졌으며, 삼림 내 묵논 일부 지역에서 드물게 후기천이 단계에서 오리나무군락이 분포하는 것으로 확인되었다. 이러한 군락의 발달은 대기후적, 지리적 조건과 관계없이 유사한 패턴을 보였다. 묵논식생의 천이단계는 일년생식물기-다년생식물기-관목식물기-교목림기로 발달해가는 천이단계로 구분할 수 있으나 중기묵논에서는 단계별 우점종이 뚜렷이 구분되지 않고 여러 종이 유사한 우점도로 혼생하였다. 군락분류를 통한 우리나라의 연차별 묵논의 식생특성을 분석한 결과, 새로운 생태복원모델로 관심이 높아지는 묵논식생의 변화양상을 파악하였으며, 이러한 결과는 휴경지의 생태복원 및 보전을 위한 기초 자료로써 매우 유효한 정보를 제공하게 될 것으로 기대된다.
