| 摘要: |
| 对福建省水温分层型富营养化山仔水库夏季大坝断面垂向水体的物理化学参数进行了监测分析,并应用荧光分析法结合显微镜细胞计数法,对垂向分层水体和沉积物中的浮游植物生物量、群落组成及丰度进行了分析.结果表明,水库的水温分层能够引起水化学指标的分层.夏季大坝断面水体中的浮游植物以蓝藻门微囊藻属占绝对优势,垂向分布表现为表层的浮游植物细胞数量高于底层,温跃层以下细胞数急剧减少,水温分层可能决定着浮游植物的垂向分布,底泥中的浮游植物将为水体的水华提供"种源". |

| Abstract: |
| Water quality variables and phytoplankton in Shanzi Reservoir in Fujian Province were monitored and sampled during aperiod of the summer stratification. The fluorometry and light microscopy were used to measure the phytoplankton abundance andthe biomass of phytoplankton in water column and sediment.The results showed that a clear thern}al stratification was formed insummer and could cause the stratification of the physical and chemical parameters. Microcystis, the absolutely dominant Cyanophytaspecie in Shanzi Reservoir, had a higher abundance in surface water than in bottom, and the biomass presented a sharp declinebellow the thermocline. Hence, the thermal stratification might affect the vertical distribution of phytoplankton population. Theabundant cyanobacterial cells in sediment could provide a "species of source" for water blooming in summer. |
