贵州黔东南州三板溪水库春季拟多甲藻水华特征

2011年3月13日对贵州省黔东南州三板溪水库进行春季浮游植物调查的结果表明,三板溪水库Ⅱ号采样点(下革东)发生以佩纳形拟多甲藻为优势种的拟多甲藻水华,细胞密度高达1.15×10⁷cell/L;板溪水库总氮的最低值为2.09 mg/L,总磷的最低值为0.95 mg/L,三板溪水库的总氮、总磷含量较丰富,不存在总氮或总磷是限制性因子;通过SPSS16.0统计软件分别进行Pearson 积距相关系数分析表明,氮磷比是三板溪水库发生拟多甲藻水华的主要影响原因。

Characteristics of Peridiniopsis Bloom of Spring in Sanbanxi Reservoir of Qiandongnan State of GuiZhou

Phytoplankton of spring is investigated in in Sanbanxi Reservoir of Qiandongnan State of Guizhou, peridinopsis algal bloom were found in the second sampling sites (xiagedong) of Sanbanxi Reserovir, Dominant species's species name is peridiniopsis penardiforme (Lindemam) Bourrelly. Cell density reached 1.15×10⁷cell/L; Total nitrogen, total phosphorus content rich of Sanbanxi Reserovir because of total nitrogen concentration of mininmun content was 2.09 mg/L and total phosphorus concentration of mininmun content was 0.95 mg/L,so total nitrogen and total phosphorus wasn't the growth limiting factors of peridinopsis algal bloom. Nitrogen to phosphorus ratio was the main of affect reason in Sanbanxi Reserovir by by SPSS16.0 statistical software from Pearson product correlation coefficient.
