Comprehensive utilization of dredged soil in the Yangtze estuary channel and exploration of ecological land formation in Xinhengsha

In view of the new water and sediment environment and the evolution of tidal flat in the Yangtze River estuary,and the dilemma of comprehensive utilization of the dredged soil in the deep water channel of the Yangtze River estuary ,guided by the concept of ecological priority and the Major Protection of the Yangtze River,we discuss the urgency and feasibility of the comprehensive utilization of the follow-up dredged soil.From the aspects of ecological environment shaping,protection of tidal flat resources and control of the Yangtze River estuary,we analyze ways and methods of carrying out the great protection of the Yangtze River estuary.Based on the project of Hengsha Avenue extension and silt protection,the concrete plan of comprehensively utilizing the dredged soil of the Yangtze River estuary deep water channel in Xinhengsha ecological landform after 2020 is put forward.
