摘要
于2010年8月—2011年8月对嵊泗列岛潮间带大型海藻进行调查。结果表明:共有大型海藻114种,隶属3门53属,其中红藻门33属75种,占总数的65.8%,褐藻门13属21种,占18.4%,绿藻门7属18种,占15.8%;枸杞最多(87种),金平其次(42种),马关最少(26种);79.8%海藻分布在低潮带,62.3%分布在中潮带,种类组成相似性指数中、低潮带为0.57,高、中潮带为0.15,高、低潮带为0.06;种类组成夏季(57种)>冬季(55种)>春季(52种)>秋季(46种),春季优势种有裙带菜、孔石莼、长石莼和厚膜藻等,夏季优势种为瓦氏马尾藻、粗枝软骨藻、鼠尾藻和麒麟菜等,秋季优势种为江蓠、小杉藻、鼠尾藻和石莼等,冬季优势种为萱藻、圆紫菜、鼠尾藻和日本多管藻等。
From August 2010 to August 2011, an investigation was conducted on the macroalgae in the intertidal zone of Shengsi Archipelago. A total of 114 macroalgae species belonging to 53 genera of 3 phyla were identified, among which, 75 species of 33 genera belonged to Rhodophyta, 21 species of 13 genera belonged to Phaeophyta, and 18 species of 7 genera belonged to Chlorophyta. Rhodophyta, Phaeophyta, and Chlorophyta accounted for 65.8%, 18.4%, and 15.8% of the total, respectively. The macroalgae had the largest number （87 species） in Gouqi Island, followed by in Jinping Island （42 species）, and in Maguan Island （26 species）. 79.8% of the macroalgae were distributed in low intertidal zone, and 62.3% distributed in middle intertidal zone. The similarity value of the algae composition between the low and middle intertidal zone, the middle and high intertidal zone, and the low and high intertidal zone was 0.57, 0.15, and 0.06, respectively. The species number of macroalgae changed with season and in the order of summer （57 species） 〉 winter （55 species） 〉 spring （52 species） 〉 autumn （46 species）. The dominant species also differed with season. The dominant species in spring were Undaria pinnatifida, Ulva pertusa, Ulva linza, and Pachymenia carnosa, those in summer were Sargassum vachellianum,Chondria crassicaulis,Sargassum thunbergii and Alga eucheumae, those in autumn were Gracilaria verrucosa, Gigartina intermedia suring, Sargassum thunbergii, and Ulva lactuca, and the dominant species in winter were Scytosiphon lomentarius, Porphra suborbiculate, Sargassum thunbergii, and Polysiphonia japonica.
