Abstract

Abstract

A hydrodynamic, chemical and biological joint ecosystem investigation in the Laizhou Bay and the Weihe River Estuary was carried out during the drying up of the Honghe River in June 1998.The biological oceanographic parameters, including chlorophylla concentration, phaeopigments concentration and primary productivity, are measured and analyzed.The mean value of chlorophyll a concentration is 1.331 mg/m³, chlorophyll a concentration ranges from 0.089 to 5.444 mg/m³.The mean value of phaeopigments concentration is 0.905 mg/m³, phaeopigments concentration ranges from 0.176 to 3.402 mg/m³.The patterns of chlorophylla and phaeopigments concentration horizontal distribution are similar, high concentration area is located at the Xiaoqing River Estuary, the Weihe River Estuary and adjacent area.The mean value of primary productivity are 62.49 mg/(d·m²), primary productivity ranges from 13.58 to 301.54 mg/(d·m²).High primary productivity is found at the Xiaoqing River Estuary and nearby 37.30°N, 119.47°E.The Pearson's correlation coefficient analysis results of phytoplankton biomass, zooplankton and chemical oceanographic parameters, show a closed correlation between chlorophylla, phaeopigments, microzooplankton, phosphate and silicate concentration in station grid survey, meanwhile a stronger correlation between chlorophylla concentration and tide fluctuation is found in the Weihe River.The phytoplankton growth is limited not by nitrogen nutrient but phosphate and silicate.The phytoplankton biomass and primary productivity are increased compared with history data.
