Abstract

Phytosociological study was carried out to investigate the structural characteristics of Humulus japonicus community in the Middle area of Korea. The vegetation data of total 67 $relev\acute{e}s$ were analyzed by the $Z\ddot{u}rich$-Montpellier school's method. Upper layer plant communities of Humulus japonicus were classified into four community groups : Humulus japonicus-Artemisia princeps community, Chenopodium album community, Setaria viridis-Echinochloa crus-galli community and Typical community. Lower layer plant communities were classified into five community groups : Galium spurium-Stellaria aquatica community, Equisetum arvense community, Persicaria theunbergii community, Echinochloa crus-galli-Digitaria ciliaris community and Typical community. According to the results of canonical correspondence analysis by vegetation and environmental factor, Setaria viridis-Echinochloa crus-galli community of upper layer was distributed throughout the soil with high relative light and soil hardness. Chenopodium album community appeared in the soil with high pH. Galium spurium-Stellaria aquatica community of lower layer was formed in the high soil pH. Persicaria theunbergii community and Echinochloa crus-galli-Digitaria ciliaris community were distributed in the soil with high moisture.

국내 분포하는 환삼덩굴군락의 식생구조에 대해 식물사회학적 연구를 수행하였다. 총67개 조사구에 대한 식생자료의 분석은 $Z\ddot{u}rich$-Montpellier 학파의 방법을 이용하였다. 환삼덩굴군락의 상층 식생은 쑥-환삼덩굴군락, 흰명아주군락, 돌피-강아지풀군락, 전형하위군락으로 구분되었다. 하층 식생은 쇠별꽃-갈퀴덩굴군락, 쇠뜨기군락, 고마리군락, 바랭이-돌피군락, 전형하위군락으로 구분되었다. 식생과 서식환경과의 CCA분석 결과 상층의 돌피-강아지풀군락은 토양 경도와 상대광도 높은 지역에 서식하고 흰명아주군락은 토양 pH가 높은 지역에 분포한다. 하층의 쇠별꽃-갈퀴덩굴군락은 토양 pH가 높은 지역에 발생하고 고마리군락과 바랭이-돌피군락은 토양 수분이 높은 지역에 형성되었다.
