Abstract

Qualitative and quantitative algal survey was conducted from March 2010 to December 2010 on a man-made artificial beach in the Hwawon Resort Complex in order to understand seasonal changes of algal flora. The seasonal change of algal vegetation was compared with intact natural habitat near from the experimental sites. Total 15 algal species were found at the artificial beach; 8 Chlorophyta, 3 Phaeophyta and 4 Rhodophyta. And 38 algal species were found at the natural habitat; 7 Chlorophyta, 9 Phaeophyta and 22 Rhodophyta. Dominant algal species at the artificial beach were Ulva compressa, U. intestinalis, U. prolifera, U. pertusa in winter and Urospora penicilliformis, U. intestinalis, U. compress in summer. In natural habitat, dominant algal species were U. pertusa, U. compressa in winter and Sargassum thunbergii, Ishige okamurae in summer. (R+C)/P explaining spatial distribution of seaweeds was 3.7~4.0 (warm-temperature) in the artificial beach and 2.6~3.4 (polar-temperate) in the natural habitat, respectively. The flora of artificial beach could be classified into the filamentous form (64.4%), the sheet form (21.9%), and the coarsely branched form (13.7%). There was significant difference from the two habitats representing dominant species, distributions and ratio of functional-form groups.

2010년 3월부터 2010년 12월까지 화원관광단지의 인공해빈에서 해조상의 계절적 변화에 대한 정성 및 정량조사를 실시하였다. 해조 식생의 계절적 변화는 인근의 자연서식지의 식생과 비교하였다. 인공해빈에서는 녹조류 8종, 갈조류 3종 및 홍조류 4종으로 총 15종의 해조류가 출현하였으며, 자연서식지에서는 녹조류 7종, 갈조류 9종 및 홍조류 22종으로 총 38종의 해조류가 출현하였다. 우점종은 인공해빈의 경우 겨울철에 Ulva compressa, U. intestinalis, U. prolifera, U. pertusa, 여름철에는 Urospora penicilliformis, U. intestinalis, U. compressa였으며, 자연서식지의 경우 겨울철에 U. pertusa, U. compressa, 여름철에 Sargassum thunbergii, Ishige okamurae였다. (R+C)/P 지수는 인공해빈에서 3.7~4.0, 자연서식지에서 2.6~3.4로 나타났다. 인공해빈의 해조 기능형군별 비율은 사상형 64.4%, 엽상형 21.9%, 분지형 13.7%로 분석되어 자연서식지의 기능형군별 비율과는 유의한 차이를 나타내었다.
