Frequent occurrence of cyanophyta water-blooms destroyed the ecological environment,affected on human health and sustainable development of society and economy in some areas.Cyanobacterial early-warning system can provide real-time technology support for treatment and mitigation of this environmental disaster.This paper reviews the status of cyanobacterial early-warning and monitoring technologies firstly.Then,in order to decrease the negative effect and loss caused by cyanobacteria bloom effectively,suggestions to improve monitoring system are also proposed based on the data analysis in recent years to the west Chaohu Lake monitoring.
