三峡库区冬季微囊藻水华探析

Study on Microcystis Water-bloom in Winter in the Three Gorges Reservoirs

通过分析优势藻的生长繁殖规律及其与N、P营养盐浓度、温度、流速和水深等因素的关系,探讨了水华微囊藻、铜绿微囊藻在大宁河完整生长周期所需的水域条件及死亡细胞的沉降速率,并提出了防止和抑制水华发生的措施。

The relationship between the growth and propagation laws of the dominant algae and the concentration of nutrient compounds,water temperature,flow velocityand water depth was analyzed.The water area conditions for the whole growth period of Microcystis flos-aquae and Microcystis aeruginosa in Daning River and the sedimentation velocity of dead cells were discussed.And some measures for preventing and inhibiting the water bloom were put forward.
