摘要
2008年1-6月对澜沧江干流的漫湾水电站和大朝山水电站库区进行浮游藻类调查。两库区共检出浮游藻类7门28属。藻细胞密度变化范围：大朝山库区0．06×10^6-2．28×10^6个／L，漫湾库区0．12×10^6～4．86×10^6个／L。藻类的组成和数量随环境和水文条件呈现一定的变化，1、2月份主要是蓝藻、硅藻、绿藻，3～6月份主要以硅藻为主，漫湾库区的总藻数明显高于大朝山库区。
According to the aquatic ecosystem investigation in the first half year of 2008, the composition and quantity of phytoplanktons of reservoir of cascade hydropower of Lancang river were studied, The results indicated that 7 phyla, 28 genera of phytoplankton community in the water of Lancang river were identified. The cell density of each monitoring point are 0. 06×10^6 cells/L of Dachaoshang reservoir, and 0. 12 ×10^6- 4. 86 ×10^6 cells/L. The cell density varied definitely in different seasons with the conditions of environmental factors and hydrology.
