摘要
【目的】探讨东海沿海赤潮发生与环境因子的关系。【方法】对2003-2016年东海11个赤潮监控区的调查与监测数据进行统计分析,并采用Spearman秩相关系数法研究了赤潮与环境因子关联关系。【结果】东海近岸海域赤潮发生与水温、pH与溶解氧呈显著正相关关系,与活性磷酸盐、硝酸盐等无机营养盐呈显著负相关关系。【结论】赤潮发生时水温一般为25～33℃,pH为8～9,溶解氧5～10 mg/L,营养盐处于极低值水平。
【Objective】The red tide along the coast of the East China Sea and its relationship with environmental factors was investigated.【Method】The study analyzed data from 11 red tide monitoring stations in the East China Sea from 2003 to 2016 by Spearman method.【Result】The environmental factors positively correlated with the occurrence of red tide were:water temperature,pH and dissolved oxygen,and the major negative correlations factors were active phosphate,nitrate and other inorganic nutrients.【Conclusion】During red tide outbreak,the water temperature is from 25-33℃,the pH is 8-9,the dissolved oxygen is 5-10 mg/L,and the inorganic nutrients such as active phosphate are at extremely low levels.
