Abstract: In recent years, with the intensification of human activities and reduction of sediment into the sea, some estuarine tidal flat wetlands in our country have been facing serious erosion and degradation, which poses a huge threat to the development of coastal cities. Therefore, the scientific management and rational use of estuarine tidal flat wetlands are extremely urgent. In this study, the regional chart topography data before and after the multi-phase of Yangtze Estuary deepwater channel north dyke project and the Hengsha Island land forming and silting promoting project from 1990 to 2017 were used to analyze the evolution of the wetland landforms in Hengsha Island, and the ArcGIS geographic registration, contour digitization, digital elevation model establishment, and overlay analysis were used to analyze the landform isobaths changes in morphology, terrain erosion-sediment thickness, and spatiotemporal changes of Hengsha Island. The result indicates that the implementation of the north guide dike project of the deepwater channel of Yangtze Estuary and the land forming and silting promoting project of Hengsha Island has changed the hydrological and sediment conditions to certain extent in the waters around the tidal flat wetlands of Hengsha Island, and its status of landscape erosion and deposition:1) It has greatly promoted the outward orientation of the characteristic isobaths. The maximum annual growth rate of 0, 2,and 5 m isobaths envelope area (2009-2013) is 42.13, 280.73, and 235.65 times that of the project (1990-1998). The overall envelope volume of 0-1, 1-2, 2-3, 3-4, 4-5 m isobaths shows an overall increase in 1990-1998, 1998-2009, and 2009-2013, and the tidal flat wetland shows a trend of "growing up but not extending". 2) The frequency characteristics of erosion-deposition are micro-deposition before engineering (1990-1998), micro-deposition after engineering (1998-2009), significant increase in deposition (2009-2013), and micro-erosion (2013-2017). At the same time, the reduction of sediments from Yangtze Estuary into the sea may have produced a certain impact on the development of tidal flats below the 2 m isobaths.

Key words: estuarine tidal wetland, characteristic isobaths, geomorphic erosion and deposition, engineering effects, Hengsha Island, Yangtze Estuary
