This paper firstly analyzes the historical and recent evolution of the Yangtze Estuary and Hengsha East Shoal.The Yangtze Estuary is generally stable recently and a dynamic balance is maintained for tideland resources under the application of silting-up and other solutions.This paper also analyzes the tideland changes before and after the implementation of Hengsha East Shoal regulation and utilization project.The accretion of peripheral tidal flats has contributed to improve the regional physical environment.However,the resources of -5 m shallow flats at Hengsha have a decreasing trend,it is advisable to carry out regulation works early possible and build up enclosing dikes in a controlled and appropriately phased manner,combining the use of dredged sediments and the requirement of keeping dynamic balance between tidal flats and wetland.
