Cyanobacteria Blooms Short-term Monitoring and Prevention Control Strategies
The problem of blue-green algae blooms continues to affect my country's inland lakes.Lake O in Central China has been infested by blue-green algae blooms from June to October in recent years,causing the death of water organisms,and the accumulation and odor have affected the lake's recreational function.The research was carried out in Lake O from July to October 2022.Through continuous low-altitude monitoring and research of the cyanobacteria bloom in the lake,it analyzed its lake surface distribution,combined with meteorological data to explore its drift direction and law,and predicted its develop-ment.And try to reduce its spread through physical barriers and other measures.The results show that in early July 2022,blue-green algae in Lake O were mainly distributed in the eastern part of the lake area.The number of blue-green algae in the western and southern parts was lower and no algae blooms were formed.Through meteorological data analysis combined with water quality monitoring data from automatic stations,it is predicted in advance that Cyanobacteria blooms will break through the established algae barriers from the eastern region and enter the western lake area.Therefore,the study immediately set up an algae barrier at the O Lake Bridge to control the algae bloom in the eastern area of Lake O and prevent it from drifting and spreading to other areas,so that no cyanobacteria bloom occurred in the western and southern areas of Lake O.Research shows that water quality automatic station data and drone monitoring can more accurately determine the spatial distribution of cyanobacteria,and combined with meteorological data can predict the drift of Cyanobacteria blooms.Building physical barriers to block algae based on the prediction results can effectively limit the occurrence of cyanobacteria blooms.Drift has verified the feasibility of Cyanobacteria bloom monitoring and prevention methods,and provided new ideas for early control and management of Cyanobacteria.
