Since the 20th century，the frequent sand mining activities in the upper Yangtze River have caused dramatic changes in the river topography，and the sediment deposition in the channel of the sand mining reaches has threatened navigation safety. Taking Lianshitan in the upper Yangtze River as an example，this study comprehensively analyzes its water and sediment conditions and focuses on the changes in river topography and channel conditions after the destruction of the islands and bars. Then，it puts forward a regulation scheme according to the navigation-obstructing characteristics and the external investigation. In addition to dredging and reef clearing to ensure the channel depth，damming and shoal consolidation with backfilling are combined to restore the high and complete form of the Guandaoqi central bar and thereby improve the flow-converging capacity for medium floods. Moreover，the reef clearing stone and ecological fish nest bricks are used to build an ecological conservation area and ultimately create a pleasant ecological environment. The model study shows that the proposed ecological regulation scheme is effective and provides a reference for the regulation of similar shoals.
