英文摘要<正>Analysis using historical data on the phosphate sources in Changjiang (Yangtze River) estuary show that phosphate was supplied equally from the east,south,west and north of the estuary. These sources include the Changjiang River,the Taiwan Warm Current (TWC),a cyclone-type eddy,and the 32°N Upwelling,supplying different phosphates in different times,ways and intensities.The magnitude of their supplying phosphate concentration was related with the size in the order of the Changjiang Riverthe TWC>the cyclone-type eddy>the 32°N Upwelling.The four sources supplied a great deal of phosphate so that the phosphate concentration in the estuary was kept above 0.2μmol/L in previous years,satisfying the phytoplankton growth.The horizontal and vertical distribution of the phosphate concentration showed that near shallow marine areas at 122°E/31°N,the TWC in low nutrient concentration became an upwelling through sea bottom and brought up nutrients from sea bottom to marine surface.In addition,horizontal distribution of phosphate concentration was consistent with that of algae:Rhizosolenia robusta,Rhizosolenia calcaravis and Skeletonema,which showed that no matter during high water or low water of Changjiang River,these species brought by the TWC became predominant species.Therefore,the authors believe that the TWC flowed from south to north along the coast and played a role in deflecting the Changjiang River flow from the southern side.
