Base on the conserved 16S rDNA gene of microcystis,cyanobacteria and microcystin synthetase gene B(mcyB).A duplex PCR and nested PCR were used to detect toxic species at eight scenic sites,including 108 water samples in Guangzhou of Guangdong province in three seasons.Results show that total positive ratio of toxic Microcystis was 38.9% in winter,94.4% in summer,and 92.5% in autumn.This study demonstrated that toxic Microcystis distributed in winter,summer and autumn and Microcystins pollutions in Guangzhou scenic sites was mainly in summer and autumn.
