摘　　要：Cyanobacteria are the Earth’s oldest oxygenic photoautotrophs and have had major impacts on shaping the biosphere.Their long evolutionary history($3.5 bya)has enabled them to adapt to geochemical and climatic changes and,more recently,anthropogenic modifications of aquatic environments,including nutrient overenrichment(eutrophication),water diversion,withdrawal。Cyanobacteria are the Earth＇s oldest oxygenic photoautotrophs and have had major impacts on shaping the biosphere. Their long evolutionary history （-3.5 bya） has enabled them to adapt to geochemical and climatic changes and, more recently, anthropogenic modifications of aquatic environments, including nutrient overenrichment （eutrophication）, water diversion, withdrawal, and salinisation [1].
