| 摘 要： | 通过对湿地水体水样中惠氏微囊藻、铜绿微囊藻和绿色微囊藻的培养，检测经湿地净化后水体和湿地外周水体中微囊藻数量变化．比较得知，经湿地净化水样中的蓝藻细胞总数的上升趋势明显低于湿地外周水样．3种微囊藻的繁殖速度，在湿地外周水样中为：铜绿微囊藻〉〉惠氏微囊藻〉绿色微囊藻，铜绿微囊藻为优势种群；在经湿地净化水样中为：惠氏微囊藻≈铜绿微囊藻〉绿色微囊藻，3种微囊藻的比例与培养前相同，且优势藻群并非微囊藻类．结果表明，湿地能有效改变微囊藻的繁殖速率和水体中藻类的优势种群，明显抑制水体中的蓝藻数量，达到净化水质的目的．

| Abstract: | After cultivating Microcystis wesenbergii,Microcystis viridis and Microcystis aeruginosa in the water samples collected from the peripheral and internal wetlands of Lake Dianchi, the changes in the number of Microcystis were detected. From the data, the up- ward trend of the total number of Cyanobacteria cells in the water samples of the internal wetland was significantly lower than the peripheral water wetlands. In the water samples from the peripheral wetland, three species of Microcystis reproduction speed was Microcystis aeruginosa 〉〉 Microcystis wesenbergii 〉 Microcystis viridis, and Microcystis aeruginosa was the dominant algae. In the water samples of the internal wetland, the reproduction rate of Microcystis was as followed：Microcystis aeruginosa ≈ Microcystis wesenbergii 〉 Microcystis viridis. Three kinds of Microcystis had the same proportion compared with the sample before being cultivated, and Microcystis was not the dominant algae. The results demonstrated that wetlands could change the reproduction rate of Microcystis effectively and the dominant algae populations, inhabit the number of Cyanobacteria in water significantly, then could reach the purpose of water purification. |
