摘    要:利用历史统计数据,以2000-2016年渤海发生的赤潮事件为对象,研究了赤潮发生的时空动态、赤潮生物的生态演替以及与温度、营养盐、地理水文要素和厄尔尼诺-南方涛动事件(ENSO)的关联。结果表明:(1)时间分布上,赤潮高发期为5-8月,2-4月和11月发生频次较低;(2)空间分布上,赤潮集中发生在河北秦皇岛-唐山-辽宁绥中近岸、辽宁营口鲅鱼圈附近以及渤海湾近岸海域;(3)共检出赤潮生物40种,包括甲藻18种、硅藻18种、金藻2种、褐胞藻1种,另外还有原生动物1种,其中甲藻门的夜光藻(Noctiluca scintillans)、裸甲藻(Gymnodinium sp.)和亚历山大藻(Alexandrium sp.),金藻门的球形棕囊藻(Phaeocystis globosa)以及硅藻门的中肋骨条藻(Skeletonema costatum)、海链藻(Thalassiosira sp.)和角毛藻(Chaetoceros sp.)是渤海爆发频次较高的赤潮优势种,另外海区的赤潮生物存在着明显的生态演替现象;(4)温度和营养盐结构对赤潮爆发及其优势种演替起到关键作用,高通量的陆源污染物与弱化的水动力相互叠加为诱发赤潮提供了条件,而厄尔尼诺效应强度与赤潮发生面积呈显著正相关(P<0.05)。

Abstract:According to the historical statistics of red tides occurred in Bohai Sea from 2000 to 2016, the spatial-temporal dynamics of red tides and the ecological succession of red tides creatures along with the correlations with tempreture, nutrients, geographical factor and ENSO were studied. The results indicated that: (1)The peak period of red tides was from May to August, while the low period was from February to April and November; (2)Red tides were concentrated in the offshore area of Qinhuangdao-Tangshan-Suizhong, Bayuquan and Bohai Bay; (3)There were 40 organisms causing the red tides be checked out in Bohai Sea, among which 18 were Dinoflagellate, 18 were Diatom, 2 were Chrysophyte, 1 was ChattonellaSand 1 was Protozoa. Noctiluca scintillans, Gymnodinium sp., Alexandrium sp., Phaeocystis globosa, Skeletonema costatum, Thalassiosira sp.and
Keywords:Bohai Sea  red tide  spatial-temporal dynamics  seasonal succession  influence factors
