Abstract

Abstract

The Deng zhou Shoal shaped in a stripped sub-water sandbar is located in south of the Miaodao Channel. Comparing the charts of 1974 with 1959,there is little change on the shoal with its to pography and water depth.It shows that the shoal had been in a state of dynamical equilibrium.Detailecl analysis on the sub-water geomorphology,sediments composition and environmental conditions,it can be deduced that the Dengzhou Shoal is one part of the ebb-tidal sand ridges formed after the period of Holocene.It is like a submerged barrier preserved the Penglai northeastern coast from wave incursion.But since 1985,some companies have begun to dredge on the shoal and caused the huge sand lost.Till 1990,the resident area surrounded by the-5 misobath line was changed from the original 3.96 km² to 0.5 km².Estimated by the reservoir model,the shoal can be recovered but cannot returned to the original scale.
