大亚湾澳头增养殖区赤潮与环境的关系研究 Ⅰ.浮游植物总生物量与环境因子的关系

The Research of the Relation Between Red Tide and Environmental Factors in Aotou, Daya Bay

根据大亚湾澳头海域增养殖区 1997- 1999年的赤潮监测数据 ,采用误差反向传播人工神经网络模型 ,研究了浮游植物总生物量与理化、气象等环境因子的关系 .结果表明 ,水温、盐度、磷酸盐、无机氮、铁、锰、硒、钴、风速、风向等因子影响较大 ,为准确预测赤潮 ,选取合理的预报指标提供依据 .

The relation between the total biomass of red tide phytoplankton and the environmental factors such as physico_chemical and meteorological factors was investigated based on the observing data of Aotou habor,Daya Bay from 1997 to 1999 by using back_propaganda artificial neural network model. The results showed that water temperature, salinity, phosphate, inorganic nitrogen, Fe, Mn, Se, Co, wind speed and wind direction are mainly influential factors of the total biomass,they are the reasonable basis in the prediction of the occurrence of red tide accurately and efficiently.
