| 摘要: |
| 滴水湖是在围垦滩涂上挖成的一个人工湖.为了解该湖泊周年轮虫群落结构特征, 于2008-2009年对滴水湖轮虫进行逐月采样研究, 对湖泊巾轮虫的种类组成、丰度及相关生态因子间的关系进行分析.共采集到轮虫12属33种, 优势种有萼花臂尾轮虫、角突臂尾轮虫、暗小异尾轮虫以及多肢轮虫等.周年轮虫丰度变化范嗣为58.3-1829.2ind./L, 四个季节间存在极显著差异, 水平空间上没有显著差异.夏、秋季轮虫丰度明显高于春、冬两季, 其中秋季最高, 平均为1087.5ind./L;轮虫丰度变化主要与绿藻密度、温度等有关。 |

| Abstract: |
| Lake Dishui is a man-made lake which was excavated in the reclaimed beach land, Shanghai.The study analyed monthly sampled rotifer from the lake between 2008 and 2009 to understand the dynamic features of planktonic rotifer.We also studied the specific composition, abundance and related ecological variables of rotifers.Altogether 33 species of rotifers, belonging to 12 genera were identified.The dominant species were including Brachionus calyciflorus, B.angularis, Trichocerca rousseleti and Polyarthra sp.The rotifer abundance of annual varying was 58.3-1829.2ind./L.There was an extremely significant difference among the four seasons, but no significant difference among the sample stations.Apparently the abundance of rotifers in summer and autumn was higher than those in spring and winter, particularly the value in autumn was a maximum, averaged 1087.5 ind./L, The change of rotifer-abundance was mainly related to the variables, such as Chlorophyta biomass and temperature. |
