Based on the study of the horizontal distribution features of nitrate and silicate in the Changjiang River estuary and its adjacent sea areas, it is pointed out that the nutrients in the Changjiang River Diluted Water (CRDW) are transported toward two different directions simulatanously from the river mouth except in winter——one toward north or northeast to enter the southwest of the Southern Yellow Sea, the other toward south or southeast to enter the East China Sea. Hence a new viewpoint 'Bidirectional extension of the Changjiang River Diluted Water' is put forward, that is, the CRDW first flows toward southeast along the estuarine trend, and then it is separated into two parts except in winter at the river mouth, one part of the CRDW extending southward along the coast passing through the mouth of Hangzhou Bay and the sea area of the Zhoushan Islands, or extending toward southeast from the river mouth; the other turning left and extending toward northeast or northward to enter the southwest of the Southern Yellow Sea. But the water quantities and the proportion of the two parts of the CRDW are different in different seasons.
