目前，长江口正处于开发的最佳时期。随着长江口深水航道治理工程的实施和长江对岸长江口航道的通车，我国建设超深水泊位和超深水航道的时机已经成熟。在长江口外区15m深水航道基础上修建人工岛，可达20m深水航道，建成深水大港，成为长江流域陆海协同运输的桥头堡。相应地，长江口深水航道治理工程产生的大量泥沙将为横沙东部潮滩及其周围沙洲加速成陆创造有利条件。通过疏浚、加速淤积和填海三位一体，预计在未来20年内形成500多平方公里的岛群，形成长江口南港与北港之间、北港主航道两侧的次三角洲体系。
Currently,it is the best time to develope the Yangtze River Estuary.With the conduct of the Yangtze Estuary Deepwater Channel Regulation Project and the Yangtze Estuary passage across the river being opened to traffic,the time is ripe for us to build super-deep water berths and super-deep water channel.If we build a man-made island on the base of deep-water channel of 15m at the Outer Zone of the Yangtze Estuary,deep-water channel of 20m would be reached and deep-water Grand Port could be built which would become the bridgehead of land-and-sea coordinated transport in the Yangtze River Basin.Correspondently,large amount of sediment created by the Yangtze Estuary Deepwater Channel Regulation Project will create favorable conditions for accelerating the Hengsha eastern tidal flat and its surrounding sandbars into land.By the trinity of dredging,accelerative silting and the land reclamation,it is estimated to form the island groups over 500 square kilometers and shape the sub-delta system between the South Port and the North Port in the Yangtze River Estuary,and on both sides of the main channel in the north channel in the next 20 years.
