摘要
2012年3月、6月、9月和12月对青岛栈桥、威海双岛湾及荣成月湖3个典型海域大叶藻(Zostera marina)草场的附着大型藻类进行了调查,采用多样性指数、均匀度、聚类和排序等多元统计方法对各海域不同季节附着藻类的群落结构进行比较分析。结果表明:鉴定大型藻类17种,隶属3门14属,其中红藻门4属5种、褐藻门4属4种和绿藻门6属8种;三海域附着藻类种数最大值均出现在春季的栈桥和月湖(均为7种),最小值出现在秋季和冬季的月湖(均为1种);三海域附着藻类生物量最高值均出现在春季,而最低值分别为秋季(栈桥)、冬季(双岛)和夏季(月湖);栈桥的Shannon多样性和Pielou均匀度指数最低,双岛的物种多样性指数最高;一年中夏季的物种多样性和均匀度指数最高,冬季最低;聚类和排序结果表明,不同季节附着藻类群落结构在海域间和海域内不同采样点间均呈现显著性差异。季节变化和地域的差异对大叶藻附着藻类的群落结构特征有着重要影响。
In order to study the structural characteristics of the epiphytic algal community of eelgrass（ Zostera marina） along Shandong Peninsula,we conducted investigations at Zhanqiao,Qingdao,Shuangdao Bay,Weihai,and Moon Lake,Rongcheng in March（spring）,June（summer）,September（autumn） and December（winter） 2012. Epiphytic algal communities of eelgrass in different seasons were comparatively analyzed regarding its diversity index and evenness index using cluster analysis and multi-dimensional scaling analysis（MDS）. In total,17 species were identified,belonging to 3 classes and 14 genera. Among them,there were 4 genera and 5species of Rhodophyceae,4 genera and 4 species of Phaeophyceae,and 6 genera and 8 species of Chlorophyceae. The greatest number of species（7） was found at Zhanqiao and Shuangdao in spring,and the lowest（1） at Moon Lake in both autumn and winter. The greatest biomass was found in spring,and the lowest in autumn（Zhanqiao）,winter（Shuangdao） and summer（Moon Lake）. The Shannon diversity index and Pielou＇s evenness index were the lowest at Zhanqiao,while the diversity index was the highest at Shuangdao. The species diversity index and evenness index at the six locations were highest in summer,and lowest in winter. The epiphytic algal community structure varied significantly between at the different locations and at most of the different sampling sites of same locations in different seasons,indicating that seasonal variations and geographical differences played important roles in the variations of community structure.
