| 摘 要： | This paper describes the elevation and subsidence of coastal zone of southern Putian 3600 years BP, having basic characteristics of large magnitude, high frequency and fast rate. Among five times of elevation and subsidence ascertained so far, the largest magnitude of the subsidence is 12.5m, the largest magnitude of the elevation is 35.5 m, the difference of the magnitude of the elevation of beach rocks formed at the same time is 23.5 m, the average rate of the elevation and subsidence is from 5cm to 8 cm per year. The coastal elevation and subsidence over the last scores of years are of the faulted uplift zone in the south, of the faulted depression zone in the north, the average rates of the elevation and subsidence are respectively 6 cm per year and 8cm per year. In addition, it is found that the strong subsidences occurring in the past often have something to do with the big earthquakes.
