摘　　要：2006年9月与2007年7月对浙江中街山列岛岩相潮间带底栖海藻进行了调查,初步查明底栖海藻的种类组成、分布特征和温度属性。结果表明,采集到的34种海藻隶属于3门24属,其中褐藻门3属3种,绿藻门4属5种,红藻门17属26种。在波浪和潮汐作用下,潮间带出现局限分布种和选择性分布种,鼠尾藻(Sargas-sum thunbergii)、珊瑚藻(Corallina officinalis)和石莼(Ulva lactuca)等在调查的岛礁广有分布;红藻门种类在调查海域的出现频率为67.8%,为优势门类,褐藻门种类在该海域的总体水平分布基本呈均匀状态;91.2%的调查种类分布在低潮带,种类数垂直分布均为低潮带>中潮带>高潮带,具有明显的垂直分带现象,且温度属性以亚热带区系种类占绝对优势。We conducted a survey to study the species composition,distribution characteristics and temperature feature of the benthic algae in the rocky intertidal zones of Zhongjieshan Archipelago of Zhejiang Province in September 2006 and July 2007.Results show that 34 species are identified to belong to 3 phylums and 24 genera,among which 3 species of 3 genera belong to Phaeophyta,5 species of 4 genera belong to Chlorophyta,and 26 species of 17 genera belong to Rhodophyta.Topical and selective distribution species influenced by wave and tide are identified in the intertidal zone.Sargassum thunbergii,Ulva pertusa and Corallina officinalis are mostly found in the survey area.Rhodophyta is the dominant species,with frequency of occurrence being 67.8%,and Phaeophyta shows a rather uniform horizontal distribution.91.2% of the species are identified in low tide zone,showing an obvious vertical distribution of the species number： low tide zone mid tide zonehigh tide zone,and the absolute dominant species are sub-tropical ones.
