对2011年8月河北省近岸海域海水理化因子与水母密度进行了灰色关联度分析。结果表明,理化因子与水母密度关联度排列顺序为活性磷酸盐>无机氮>COD>溶解氧>温度>盐度。活性磷酸盐和无机氮是影响河北近岸海域水母密度的主要因素
Gray relational analysis was conducted on the physicochemical properties of seawater and the density of jellyfish in coastal waters of Hebei Province in August 2011. The results showed that the order of physicochemical factors and jellyfish density was active phosphate> inorganic nitrogen> COD> dissolved oxygen> temperature> salinity. Active phosphate and inorganic nitrogen are the main factors affecting the density of jellyfish in coastal waters of Hebei
