摘要
2007年5·29太湖供水危机后,大力治理太湖10多年,已取得阶段性成果,但蓝藻密度仍持续升高、蓝藻年年暴发。本文通过实地调查和收集资料,分析了2007—2020年太湖蓝藻持续暴发涉及的多个因素,主要为富营养化、藻密度高、水温高(自然因素的代表),据此提出消除蓝藻暴发的策略。该研究成果对今后太湖流域全面消除蓝藻暴发具有一定的参考价值。
After the water supply crisis in Taihu Lake on May 29,2007,efforts have been made for the lake treatment for more than 10 years,and phased results have been achieved.However,the density of cyanobacteria continues to rise and cyanobacteria outbreaks occur every year.Based on field investigation and data collection,this paper analyzes several factors involved in the continuous outbreak of cyanobacteria in Taihu Lake from 2007 to 2020,mainly including eutrophication,high algae density and high water temperature(representative of natural factors),and puts forward strategies to eliminate cyanobacteria outbreak.The results of this study have a certain referential value to eliminate cyanobacteria outbreak in Taihu Lake basin.
