摘要：

At present, the occurrence of harmful algal bloom has become a serious environmental problem in China. A survey of the seasonal variations of algal bloom characteristics has been investigated in a shallow hypertrophic urban lake from June to October 2013 in this study. LC-MS results indicated that there are two main cyanobacteria toxins variants (MC-LR and MC-RR) during harmful algal blooms. The community structure of cyanobacteria showed that 81.04 % of total cyanobacteria biomass belongs to Microcystis spp. and the average biomass of Microcystis spp. was 2.335 mg.L-1. In addition, multivariate analyses by principal component and classifying analysis (PCCA) suggest that microcystins were mainly produced by Microcystis spp. and TP could promote MC production.
