The amplitude and the rate of coastal elevation and subsidence and the regularities of positive andnegative crustal movements are discussed emphatically in this paper, and on this basis 11 periods ofcoastal elevation and subsidence are distinguished. Each period is further subdivided into two stagesof subsidence-sedimentation and elevation-sedimentary hiatus; each stage covers a time interval of about250 years, that is to say, each period is equivalent to about 500 years. It is a new subject to study the period of recent coastal elevation and subsidence. For this signifi-cant but difficult subject, there have always been two distinctly different schools of thought relatingto the rate of coastal elevation and subsidence, the time division of sediments and the origin of highbeach rocks. Therefore, the authors welcome the valuable comments or criticisms on this paper fromspecialists and scholars.
