摘 要: 在数据库技术的支持下,应用灰关联分析方法对2001年10月至2002年7月粤东柘林湾海域9个调查站点海水样品的理化、生物实测数据进行数据分析,从磷酸盐(PO4-P)和硅酸盐(SiO3-Si)等12项理化、生物因子中找出影响中肋骨条藻(Skeletonema costatum)细胞密度的关键因子。结果表明,浮游动物的个体数、铁(Fe)、水温和浊度是影响柘林湾中肋骨条藻细胞密度的关键因子。 By the Support of database technology, we apply the grey relation analysis method to analyze the data of samples taken during the period from October 2001 to July 2002 at 9 stations in Zhelin Bay, and find out the key factors that affect the density of Skeletonema costatum from twelve physicochemical and biological factors such as phosphate (PO4 -P), silicate (SiO3-Si), etc. The results indicate that zooplankton individuals, Fe, water temperature and turbidity are the key factors that affect the density of Skeletonema costatum.
