| 摘 要： | 铜绿微囊藻（Microcystis aeruginosa）是常见的水华蓝藻,对湖泊和水库的环境造成恶劣影响.在室内研究了温度和光照度对铜绿微囊藻生长的影响,以期为水华的监测和分析提供数据支持.研究结果表明：铜绿微囊藻喜好高温,在水温30～35,℃时生长最佳,在水温30,℃时获得最大细胞密度;而水温低于20,℃时生长缓慢.铜绿微囊藻对光照度要求不高,较低光照度即可快速增长,光照度2,000～6,000,lx适宜铜绿微囊藻快速增殖,在4,000,lx时生长最快.

| Abstract: | The Microcystis aeruginosa is one of the harmful Cyanobacteria species causing abominable environmental conditions of lakes and reservoirs.Effects of water temperature and illumination on the cell proliferation of this microalgal species were done in the laboratory in order to help the monitoring and analysis of water blooms.The results showed：the micro-alga preferred higher water temperature and the optimal temperature for M.aeruginosa to grow was 30-35,℃,and the highest cell density was obtained in 30,℃ condition.On the other hand,this microalga grew very slowly when the water temperature was less than 20,℃.This microalga did not request higher illumination,and grew best in 4,000 lx condition.The optimal illumination for its proliferation is about 2,000-6,000 lx. |
