Microbial Control of Cyanobacterial Blooms in Erhai Lake

Erhai Lake is a plateau lake of significant ecological and socio-economic value. In recent years, continuous external inputs of nitrogen and phosphorus, together with internal factors, have intensified eutrophication, leading to a markedly increased risk of cyanobacterial blooms. Traditional physical and chemical control methods are constrained by high costs and considerable ecological risks. In response to the needs of bloom management in Erhai Lake, this paper systematically reviews its hydrological and ecological characteristics, as well as the core mechanisms and mainstream application technologies of microbial algal control, providing methodological references for the management of cyanobacterial blooms in plateau lakes.
