| 摘 要： | 拟浮丝藻是我国水华蓝藻的一个新记录属,我国对此类水华缺乏研究,成都也未曾有此类报道。2008年7~8月,在原成都世界乐园犀池内首次暴发了大规模拟浮丝藻水华。为了解犀池拟浮丝藻水华的成因,对犀池2007~2008年监测资料进行了分析,研究表明:犀池富营养化正以每年平均8.1%的速率不断加剧,大规模发生拟浮丝藻水华的营养指数临界值为85,水温为25℃~30℃,pH=8.2~8.8,较小的氮磷比值(TN∶TP=10)有利于拟浮丝藻水华生长。

| Abstract: | Planktothricoides is a newly recorded genus of water-blooming cyanobacteria in China.There is little research on it even no report concerned in Chengdu.While from July to August in 2008,a large scale of Planktothricoides bloom broke out in the Xichi Lake for the first time.In order to investigate the formation causes of Planktothricoides bloom here,the data monitored during 2007~2008 were analyzed.It showed that the eutrophic state was getting stronger in Xichi Lake with an average annual rate of 8.1%.For a... |
