摘　　要：雅砻江拥有丰富的水能资源,桐子林水电站位于流域的最下游,浮游藻类研究较少。有必要监测桐子林水电站施工期和运行期的水体理化性质,分析浮游藻类变化。研究发现,施工期和运行期水质为Ⅰ~Ⅱ类,硅藻为主要类群;运行期,浮游藻类数量减少,但密度和生物量增加;pH、总氮(Total Nitrogen,TN)为限制性环境因子,高锰酸盐指数(Permanganate Value,PV)为抑制性环境因子。因此,持续监测水体理化性质和浮游藻类变化,关注pH和TN含量至关重要。The Yalong River has abundant hydropower resources,and the Tongzilin Hydropower Station is located at the downstream of the basin,with relatively little research on planktonic algae.It is necessary to monitor the physical and chemical properties of the water body during the construction and operation periods of Tongzilin Hydropower Station,and analyze the changes in planktonic algae.Research has found that the water quality during the construction and operation periods is classified as ClassⅠ~Ⅱ,with diatoms being the main group;during operation,the number of planktonic algae decreases,but their density and biomass increase;pH and Total Nitrogen(TN)is the limiting environmental factor,while Permanganate Value(PV)is the inhibitory environmental factor.Therefore,it is crucial to continuously monitor the physical and chemical properties of water bodies and changes in phytoplankton,while paying attention to pH and TN content.
