摘要
根据大亚湾核电站运行前后的环境与浮游植物相关资料,对其环境变迁与生物响应进行了相应分析。结果发现,核电站运行后,大鹏澳区域平均水温上升约0.4℃;核电站邻近水域无机氮的含量逐年增加,活性磷酸盐与硅酸盐的含量在经历一个时滞后逐年减少,至2000年又恢复了平衡;20世纪90年代初期,大亚湾浮游植物种类较丰富,数量通常是春、夏季较高,秋、冬较低。核电站运行后浮游植物种群结构明显变化,首先是种类数量显著减少,其次是秋末至冬初细胞数量显著升高,就种群组成而言,甲藻与暖水性种类的数量有增多的趋势,同时网采型浮游植物数量明显减少,但叶绿素a含量变化不大,间接地反映了群落组成的小型化趋向。
Based on the data from 1991 to 2001, the environmental change and biological response were analyzed. The result showed that during the past 10 years, Total inorganic nitrogen gradually increased, silicate and phosphate gradually decreased from 1996 to 2000 and then returned to former level. After the nuclear power station running, the average temperature of the investigation area inereased about 0.4℃. In recent years, phytoplankton distinctly went up during the end of autumn and the beginning of winter, the amount of pyrophyta and warm-water species generally increased and net-phytoplankton generally decreased.
