摘要
2011年3月至2012年3月对西昌邛海湿地浮游藻类的种类、数量进行了调查。结果表明,西昌邛海湿地共发现浮游藻类8门69属l02种,其中绿藻门25属34种1变种,蓝藻门16属23种,硅藻门13属19种,裸藻门5属12种,黄藻门4属5种,甲藻门3属3种,金藻门2属3种,隐藻门1属2种。浮游藻类的密度为2.74×105～3.58×105个/L。根据浮游藻类优势种的分布和数量,结合Margalef多样性指数分析邛海湿地的水质情况,水质总体状况较好,处于贫营养,但有向富营养转变的趋势,应注意加强对湿地的管理和保护。
The species and quantities of phytoplankton in Qionghai lake wetland was investigated from March 2011 to March 2012.The results showed that there were 102 species in total,which belonged to 69 genera of 8 families.Of which,25 genera,34 taxa and 1 variety belonged to cyanophyta family,16 genera and 23 taxa belonged to bacillariophyta family.13 genera and 19 taxa belonged to chrysophytax family,5 genera and 12 taxa belonged to euglenophyta family,4 genera and 5 taxa belonged to xanthophyta,3 genera and 3 taxa belonged to dinophyta,2 genera and 3 taxa belonged to chrysophyta,1 genera and 2 taxa belonged to cryptophyta.The density of phytoplankton was significantly different,ranging from 2.74×105 to 3.58×105 ind./L.Then the water quality was analyzed according to the distribution and abundant of the predominant planktonic algae using margalef bio-diversity index.The water quality was well in general and belonged to oligotropher level,but had the potential to turn to eutrophication level.So it was necessary to protect and manage the water source of the Qionghai lake wetland.
