太平湖水库藻类的群落结构仍以绿藻为主,硅藻和蓝藻次之,其他藻类所占比例较小。在敞水区,藻类的生长丰度显示从上游至下游逐渐递减的趋势,且明显低于库湾区。藻细胞密度和生物量均在夏季出现高峰,冬季最低。和8年前的结果相比,藻类多样性下降,总种类数减少了36%,细胞数量大幅度上升,小型种类密度增加。提出了一种藻类适度产鱼潜力的新概念和依据藻类现存生物量计算藻类适度产鱼潜力的方法。计算表明,全库藻类每年的适度产鱼潜力约为454万kg。
The community structure of algae in Taiping Lake Reservoir is still dominated by green algae, followed by diatoms and cyanobacteria, while the proportion of other algae is smaller. In the open water area, the growth of algae showed a gradual decreasing trend from upstream to downstream, which was significantly lower than that of the reservoir bay. Algal cell density and biomass peaked in summer and lowest in winter. Compared with the results eight years ago, algae diversity decreased, the total number of species decreased by 36%, a substantial increase in cell numbers, small species density increased. A new concept of the potential of algae to produce fish and a method to calculate the potential of algae to produce fish properly based on the existing biomass of algae were proposed. Calculations show that the annual potential of moderately produced algae is about 450,000 kg.
