摘    要:通过对3S技术整合,提出“MMA”技术路线应用于蓝藻水华监测,包括监测、测绘、分析等关键步骤。对太湖蓝藻水华研究结果表明,总体规律一致,但又有所差异。一方面,太湖蓝藻密度( CBD)、叶绿素a( Chl-a)及水华频率分布图结果均呈现“西高东低”的空间分布规律;另一方面,太湖湖心区CBD和Chl-a浓度亦较高,而遥感监测后的水华频率图显示为无水华或频率小于1%。故应参照“MMA”技术路线,综合应用3S技术,并核验比对,弥补单项技术存在的不足,全面真实反映藻类水华情况。“MMA”技术路线既适用于水华监测,亦可推广至其他环境监测工作。

关 键 词:“MMA”技术路线  3S技术  蓝藻水华  太湖

Abstract:On the basis of 3S technologies integration, "MMA" technical route was used in cyanobacteria bloom monitoring, which included key steps of "monitoring", "mapping" and "analyzing". 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 is "west 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, "MMA" technical route was put forward to comprehensive applying GPS, GIS and RS technologies and comparing different results. The "MMA" technical 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.
Keywords:“MMA” technical route  3S technologies(GPS、GIS、RS)  cyanobacteria bloom  Tai Lake
