According to the marine ecological environmental investigation of the Hangzhou Bay in the October 2008 and thermal infrared remote sensing image of environment satellite in the same region, the features of zooplankton communities and dominant species were analyzed. The results indicated that there were two significantly different communities of zooplankton in investigation region. The abundance and biomass in east of investigation region were larger than west of investigation region, the species richness was also larger in east than west .The zooplankton in west of investigation region was made up of oligo-haline communities, e g,Labidocera euchaeta,Pleurobrachia globosa,Acanthomysis longirostris,and that in east was made up of warm-water communities e g,Euchaeta concinna,Diphyes chamissonis,Pseudeuphausia sinica. According to the satellite remote sensing image ,there were two water masses with different temperature ,and satellite remote sensing images tallied with ecological survey data, it showed consanguineous correlations between them.
