| 摘 要： | 采用超声波分离、网筛（28μm和95μm）过滤、重液（CdI-KI)浮选等方法，对采自厦门西港的7份沉积物样品进行了分析鉴定。结果表明，厦门西港有甲藻孢囊5属10种，其中小型亚历山大藻（Alexandrium minutum)为中国沿海首次记录。沉积物中甲藻孢囊数量范围为18.2-138ind/g沉积物（湿重），高数量密集区主要分布在内湾水域；表层至表层以下2cm沉积物中的孢囊数量明显多于3-5cm底层的。孢囊数量的分布格局与本港的地形、水交换条件密切相关，不同的养殖类型对孢囊的沉降和积累也有重要影响。

| Abstract: | Sediment samples collected from seven stations in Xiamen Western Harbour were processed qualitatively and quantitatively. Based on morphological characters of the cyst and motile cells germinated from some specimens, 10 species of cysts that belong to 5 genera were identified, of which Alexandrium minutum was firstly recorded in China seas. The number of dinoflagellate cysts ranged from 18.2-138 cells per gram of wet sediment. There was a higher concentration of cysts in the inner harbour. The cysts in the 0-2cm section of sediment below the bed were much more abundant than that in the 3-5cm section within the core. The pattern of cyst distribution is much concerned with the topography and water exchange conditions in the harbour, and also with a variety of marine culture activities that may have an important impact on the cyst depository and accumulative process. |
