| 摘 要： | 于１９９０年３月－１９９２年６月对中国南海大鹏湾盐田附近海域的夜光藻种群动态及时空分布进行了综合调查，结果表明，夜光藻种群的出现期间一般为每年的１－６月，最早是１９９１年的１２月，娄量高峰期为３－５月，种群密度的波动极为显著；调查期间共发生８次赤潮，且都发生在３月初至５月初；大鹏湾夜光藻赤潮的发生特点是，赤潮的发生和消失突然，持续时间短，一般不超过３ｄ。 |

| Abstract: | Seasonal and geographical distributions of Noctiluca scintillans in Dapeng Bay, the South China Sea, were investigated from March 1990 to June 1992. The first occurrence of N. scintillans in the plankton was in January for 1990 and December for 1992. The density fluctuated remarkably, but increased to a peak between late March and early May. Afterward, the populations declined rapidly, and disappeared completely from the plankton. The time of disappearance differed slightly, depending on the year; it disappeared by the beginning of June in 1990, in late May in 1991 and late June in 1992. There were eight N. scintillans blooms (indicated by pink patches and sticks of Noctiluca covering the water surface in the study area) throughout the investigation. Cell densities during blooms were generally higher than 104 cell/L. The highest density of 2.8 ×105 cell/L was observed at S1 on April lst, 1990. The following were observed during the N. scintillans blooms that occurred in Dapeng Bay: (1) the blooms occurred and disappeared abruptly; (2) in general, the blooms did not continued for over three days; (3) the intervals between two neighbor blooms were generally short. As noted in previous studies, N. scintillans population densities in the center of the Bay, and surface water were higher than those in the coast and near bottom. |
