摘　　要：本文分析了 1 999年 1 2月至 2 0 0 1年 2月采自厦门杏林湾水库的水样数据 ,结果表明杏林湾水库浮游植物群落中蓝藻数量最大 ,硅藻次之 ,浮游植物群落表现出小型化 ,数量大的特点 ,个体数量最大值出现在 6月 ,最小值出现在 2月 ,应用灰关联分析方法进行数据分析 ,在水温、水深等 1 1项环境因素中找出影响浮游植物密度的主要因素 .结果表明 ,水温、溶氧量、盐度、透明度、pH、化学耗氧量、总磷是影响厦门杏林湾水库浮游植物密度的主要因子 .This paper embodies the results of phytoplankton in Dec.1999 to Feb.2001,in The Xinglin Bay Reservoir,Xiamen.The results show that Cyanobacteria ('blue green algae') and diatoms (Bacillariophyceae) make up the majority of the phytoplankton density for much of the active growing seasons. Diminution in size of phytoplankton occurs .Relationship between phytoplankton density and environment factors in Xinglin Bay Reservoir have been studied by grey relationship analysis method. The main environment factors of affecting phytoplankton density have been found in accordance with grey relationship degree.The water temperature,DO,salinity,water transparency, pH and chemical oxygen demand were more important factors for the phytoplankton density than other factors.
