| 摘 要： | 2012年7月和10月分别对白云湖中华鳖养殖池塘的浮游植物群落结构进行了调查.结果表明：7月采集到浮游植物5门23种,10月采集到5门36种,种类组成上均以绿藻门种类最多,其次是蓝藻门或者硅藻门；7月池塘浮游植物优势种的优势度为0.02～0.32,优势种数共10种；10月份优势种的优势度为0.02～0.37,优势种数共13种；7月份池塘浮游植物平均密度为4.70×107 ind/m3,变化范围为（0.75～12.5）×10^7 ind/m3,10月平均密度为13.16×107 ind/m3,变化范围为（2.88～18.2）×10^7 ind/m3;7月份浮游植物生物量8.10～90.70 mg/L,平均为35.57 mg/L,10月份生物量为23.10～295.86 mg/L,平均为165.55 mg/L,浮游植物优势种的种类种群、密度和生物量都存在时间和空间上的差异.

| Abstract: | The research on the phytoplankton community structure in the Trionyx sinensis culture pounds of Baiyun lake was conducted in July and October of 2012 respectively. The result indicated： there were 23 species in July and 36 Species in October belonging to 5 phyla, and Chlorophyta was the dominant species in both studies, Cyanophyta or Bacillariophyta following. The dominant phytoplankton species were 10 and the in- dex ranged from 0.02 to 0.32 in July, and that were 13 and the index ranged from 0.02 to 0.37. The density of the phytoplankton was between 0.75 and 12.5×10^7 ind/m3 with the mean value of 4.70×10^7 ind/m3 in July, and the density was between 2.88 to 18.2×10^7 ind/m3 with the mean of 13.16×10^7 ind/m3 in October. The biomass was between 8.10 to 90.70 mg/L with the mean of 35.57 mg/L in July, and that was between 23.10 to 295.86 mg/L with the mean of 165.55 mg/L in October. The difference on the dominant species, the density and the biomass of the phytoplankton was found in time and space. |
