Application of Fluorescence Technique in Early Warning Monitor to Cyanobacteria Bloom-forming in Taihu Lake

As cyanobacteria bloom-forming in Lakes Occurred frequently,reinforcing the monitoring of algae in water source area has become an environment problems which was concerned by environmental protection、water conservancy and academe.The fluorescence technique was applied in analyzing the basic characteristics of cyanobacteria bloom-forming in three Suzhou water source areas in Taihu Lake.The result indicated that:(1) The development of cyanobacteria bloom-forming in Suzhou water source area in Taihu Lake was mainly affected by the hydrological and meteorological condition.(2) The change trend of cyanobacteria bloom-forming was perfectly reflected by the blue-green alga sensor based on the fluorescence technique.(3) Because of the excellence for fast determining、easy comparing and continuous track monitoring,the fluorescence technology played an influential role in early warning monitor of cyanobacteria bloom-forming in the Tai Lake.
