摘要
在青岛潮间带布设了显浪咀、太平角和石老人3个断面,进行了为期1 a（2006年8月-2007年11月）的大型底栖海藻资源调查研究。结果表明：1.青岛潮间带大型底栖海藻群落的种类组成中红藻种类最多,其次是褐藻,绿藻最少。2.群落中大型底栖海藻的生物量有明显的季节变化：春季〉夏季〉秋季〉冬季;生物量在垂直分布上表现出中、低潮带均大于高潮带;在水平分布上无明显差异。3.底栖藻类群落优势种无季节性变化,第一优势种为孔石莼。4.采集到大型底栖海藻43种,其中红藻门22属24种,占55.8%;褐藻门9属11种,占25.6%;绿藻门6属8种,占18.6%。
Three cross sections at Xianlangzui, Taipingjiao and Shilaoren in the intertidal zone of Qingdao were set and the communities of benthic marine macroalgae were investigated from August 2006 to November 2007. Results showed that： 1. In the intertidal zone of Qingdao, species of Rhodophyta played a dominant role in the composition of the benthic marine macroalgae community, followed by Phaeophyta and then Chlorophyta. 2. The biomass of the community changed with the season too, and a seasonal variation of Spring 〉 Summer 〉Autumn〉Winter was obtained. In the vertical distribution the biomass in the low-intertidal zone or mid-intertidal zone was greater than that in the high intertidal zone, but no remarkable difference was found among the three cross sections in the horizonal distribution. 3. The dominant species had no seasonal variation, and the first dominant specie was Ulva. pertusa Kjell. 4. During the four surveys, 43 species of benthic marine macroalgae were collected, among which 24 species（belonging to 22 genera） were Rhodophyta , 11 species（belonging to 9 genera） were Phaeophyta and 8 species（belonging to 6 genera） were Chlorophyta.
