青岛太平角岩相潮间带大型海藻群落初步调查

对青岛太平角(36°02′N,120°21′E)岩相潮间带大型海藻群落进行了为期1年(2010年5月-2011年4月)逐月的定性调查研究。结果表明:1.采集到大型海藻3门36种,其中红藻门16属19种,占52.8%;褐藻门7属10种,占27.8%;绿藻门5属7种,占19.4%。2.青岛太平角潮间带大型海藻群落的种类组成中红藻种类最多,褐藻其次,绿藻最少。3.青岛太平角潮间带群落中大型海藻的种类组成和藻总量(株)有明显的季节变化:春季海藻的种类和数量都非常大,秋冬季节其次,夏季海藻种类和数量最少。4.孔石莼、鼠尾藻和珊瑚藻为青岛太平角岩相潮间带大型海藻群落的最常见种。5.青岛夏季绿潮藻种浒苔是由其他海域漂流而来,且较其他藻种更适应夏季较高水温,使其短时间内迅速生长。

Investigation on Community of Macroalgae in the Rocky Intertidal Zone of Taiping jiao in Qingdao

The rocky intertidal zone of Qingdao Taipingjiao (36°02′N ,120°21′E)were set and the com‐munities of marine macroalgae were investigated monthly from May 2010 to March 2011 .Results showed that :1 .A total of 36 species of 3 phylum were collected ,among which 19 species( belonging to 16 genera) were Rhodophyta ,10 species( belonging to 7 genera) were Phaeophyta and 7 species( belonging to 5 genera) were Chlorophyta .2 .In the rocky intertidal zone of Qingdao Taipingjiao ,spe‐cies of Rhodophyta played a dominant role in the composition of the marine macroalgae community , followed by Phaeophyta and then Chlorophyta .3 .The quantities and species of the macroalgae changed seasonally and a seasonal variation of Spring > Autumn = Winter > Summer was obtained .4 .The region's most common species are Ulva pertusa ,Sargassum thunbergii and Kappaphycus .5 .Entero‐morpha prolif ra ,the main algal of green tide in Qingdao is drifting from other sea area ,and it is more adapted to higher sea water temperatures than other algae species ,making it a short - time dominant species .
