| 摘 要： | 目的]研究2014年四十里湾一次海洋卡盾藻赤潮发展过程及其成因。方法]根据2014年8月7日至9月28日烟台四十里湾海域一次海洋卡盾藻(Chattonella marina)赤潮的监测数据,对赤潮生消期间的水文、生物、化学要素进行了分析。结果]赤潮面积约30 km~2,赤潮生物最高密度达2 910 000个/L。该海域充足的氮营养盐,尤其是NH_4-N浓度的突然升高、相对较低的PO_4-P浓度、适宜的盐度和水温等理化环境及低光照、低气压的气象条件是此次赤潮发生的关键因子。结论]该研究可为今后赤潮暴发防控提供借鉴。

| Abstract: | Objective] To study the causes and bloom process of a red tide species of Chattonella marina in Sishili Bay in 2014.Method] According to the investigated data of a red tide caused by Chattonella marina in Yantai Sishili Bay from Aug 7 to Sept 28,2014,the hydrometeorology,biology and chemistry parameters during the harmful algal bloom were analyzed.Result]The red tide area was about 30 km2 and the cell density of red tide algae was up to 2 910 000 cells/L.Adequate nitrogen nutrient,low PO4-P concentration,low salinity,low light and favorable hydrometeorological conditions provided a good physical and chemical environment for the occurrence of red tide.Conclusion] The study can provide reference for the prevention and control of Chattonella marina outbreaks in the future. |
