摘    要:为了掌握富春江水库浮游植物群落特征,探寻其与环境因子的关系,于2006年1月至2007年12月,对其进行了20次采样调查.鉴定结果表明富春江水库共有浮游植物107种,浮游植物密度范围在0.21×10~5-3.01×10~7cells/L之间.浮游植物组成随季节变化有所不同,春季绿藻、隐藻、硅藻占优势,夏季蓝藻和硅藻占优势,秋冬季硅藻、隐藻占优势.浮游植物群落结构受水文条件的影响较大,浮游植物密度与水体温度呈显著正相关,与透明度在不同范围内表现出不同的相关关系;与TN、TP在不同范围内表现出不同的相关关系,与TN/TP及可溶性硅呈显著正相关.库区总氮和总磷浓度均很高,足够满足藻类生长需要;TN/TP较低,基本在8-30之间,说明氮磷含量不是富春江库区藻类生长的限制因子.水文季节性变化会明显地影响浮游植物群落结构和密度的季节性变化,特别是降雨、水温及水力滞留时间等因子是影响水库浮游植物群落结构及密度变化的主要因子.

关 键 词:富春江水库  浮游植物  时空变化  环境因子

Abstract:During January 2006 to December 2007,phytoplankton and environmental factors were monitored for twenty times in Fuehunjiang Reservoir.A total of 107 taxa were identified by microscope.The phytoplankton density was ranged from 0.21 × 10~5-3.01×10~7 cells/L.The specific composition of phytoplankton community changed with the seasons.Bacillariophyta,Chlorophyta and Cryptophyta dominated in Spring;Cyanophyta and Bacillariophyta dominated in Summer;and Bacillariophyta and Cryptophyta dominated in Autumn and Winter.The structure of phytoplankton community was obviously affected by hydrological conditions.There WBS significant positive correlation belween phytoplankton density and water temperature.The correlation coefficients between phytoplankton density and transparency,TN,TP varied in different ranges.Phytoplankton density was significant positive correlations with water temperature,TN/TP,and soluble silicon.TN and TP concentrations were high enongh to meet the needs of algal growth.Low N/P between 8 to 30 showed that nitrogen and phosphorus content may not be limiting factors forthe growth of algae in Fuchunjiang Reservoir.The seasonal change of phytoplankton community and density were obviously affected by seasonal change in hydrological,especially by precipitation,water temperature and water retention time.
Keywords:Fuchunjiang Reservoir  phytoplankton  spatio-temporal changes  environmental factors
