| Abstract: |
| The distributions of chlorophyll a concentration,primary production and new production were observed in the Laizhou Bay of the Bohai Sea in both spring and neap tides during July 1997.The results showed that there were marked features of spatial zonation in the surveyed area,due to the differences between the geographic environment and the hydrological conditions.Chlorophyll a,primary production and new production were all higher in spring tides than that in neap tides in the Laizhou Bay.The highest values of these parameters were encountered in the central regions of the bay.At most stations,chlorophyll a concentrations at the bottom were higher than that at the surface.The results of size-fractionated chlorophyll a and primary production showed that contributions of nano-combining pi-coplankton (>20 μm) to total chlorophyll a and primary production were dominant in phytoplankton community biomass and production of the Laizhou Bay.The environmental factors,primary production and new production in the Laizhou Bay are compared with other sea areas. |
