Abstract：We utilize the cyanobacteria A which isolated and purified form Qinghai Lake as experimental material. Study the effects of the short-term intensified UV-B radiation (240μW/cm2) on the content of biomass, chlorophyll, carotenoid, protein, MDA and proline. The results shows that after short-term intensified UV-B radiation the content of biomass was significant declines, the content of chlorophyll、carotenoid and protein was increased, meanwhile the contents of MDA and proline was decreased. Above states the cyanobacteria A in Qinghai Lake has evolved a adaptive mechanism after long-term intensified UV-B radiation, lipid peroxidation was reduced resulting in attenuation of damaging effects of UV-B, and in some degree UV-B radiation promotes the synthesis of photosynthetic pigment and protein.
