The Application of“MMA”Technical Route in Tai Lake Cyanobacteria Bloom Monitoring

On the basis of 3S technologies integration,MMAtechnical route was used in cyanobacteria bloom monitoring,which included key steps ofmonitoring,mappingandanalyzing. The results of Tai Lake cyanobacteria bloom monitoring were so similar,but also had something different. On one side,the cyanobacteria density( CBD),Chl-a concentration and cyanobacteria bloom frequency distribution maps all showed a spatial distribution law which iswest high and east low. On the other,the CBD and Chl-a concentration were also high in the middle area of Tai Lake,however,the remote sensing monitoring result indicated that the cyanobacteria bloom frequency of this area was non-cyanobacteria bloom or only less than 1%.Therefore,MMAtechnical route was put forward to comprehensive applying GPS,GIS and RS technologies and comparing different results. The MMAtechnical route was helpful to cover the shortage of single technology application,and fully reflecting the actual situation of cyanobacteria bloom. It would be useful not only in algae bloom monitoring,but also in other environmental monitoring field.
