| 摘 要： | 于１９９１年３月２０－２１日在大鹏湾首次发生海洋褐胞藻赤潮。对此分析了赤潮发生前后海洋环境因素的变化及其与赤潮的关系；以风速，气压，盐度，温度，磷酸盐，硝酸盐，铵盐，铁离子等８项指标为基础，改变参数组合，对采自１９９１年３－５月特定站位（Ｓｏ）的各样方进行聚类分析和比较。结果表明，在盐度为３１－３２和水温为２０℃的适宜条件下，铁离子和风速是形成本次赤潮的主要环境要素；大量营养盐尤其是硝酸盐度的增加

| Abstract: | A Chattonella marina Hara et Chihara red tide occurred in March 20 - 21, 1991 in Dapeng Bay, South China Sea. Its Maximum cell density reached 1.4×107 cells/L. A dynamic fuzzy cluster dendrogram of samples based on eight ecological parameters (temperature, salinity, iron, atmospheric pressure, wind velocity, phosphate, nitrate and ammonia) was used to analyse the variation of environmental factors measured before, during and after the red tide outbreak. The relationship between the red tide and environmental factors is discussed. The research showed that concentration of nitrate, phosphate, ammonium and iron increased just before the red tide outbreak, and that temperature and salinity were ca. 20°C and 31.38S respectively at the start of the red tide outbreak. Deletion of wind velocity and iron changed the cluster dendrogram obviously. It is concluded that: when temperature and salinity were optimum, iron and wind velocity were the decisive factors for the initiation of red tide. The increase of macronutrients, specifilly nitrate, also played a principal role in this red tide. |
