摘　　要：使用2016年7月22日-8月12日水质自动监测浮标数据,对秦皇岛近岸海域两次赤潮的诱因进行分析。第一次赤潮由夜光藻(Noctiluca scintillans)引发,赤潮期间Chl a浓度最高达到38.84μg/L,平均水温为26℃,盐度在15.9~29.1之间大幅度波动;第二次赤潮由诺氏海链藻(Thalassiosira nordenskioldi)和丹麦细柱藻(Leptocylindrus danicus)引起,赤潮期间Chl a浓度最高达到35.12μg/L,水温较赤潮发生前升高2℃。研究结果表明,风暴潮为夜光藻赤潮的重要诱因,温盐变化也影响着赤潮生物种类的演替。Two red tide events were recorded by buoys in Qinhuangdao coastal area between July 22 and August 12 of 2016. The first red tide event was caused by Noctilucascintillans. During the bloom the concentration of chlorophyll-a was up to 38.84μg/L, with average water temperature reaching 26 ℃ and salinity fluctuating between 15.9 and 29.1. In contrast, the second red tide event was triggered by Thalassiosira nordenskioldi and Leptocylindrus danicus, with the concentration of chlorophyll-a reaching as high as 35.12 μg/L and water temperature increasing by 2 ℃. The research results indicate that the first red tide event was initiated to a large extent by the storm surge, and the changes of temperature and salinity also affect the succession of relevant species.
