According to 107 dating data including 9 kinds of paleosea level indicators which the deposit depth and tectonism correction have done, the sea level change curve in Zhujiang Delta during the past 8000 years, has been drawn. Sea level rose quickly before 6000 years, descended from 6000 years B.P. to 5500 years B.P. rose from 5500 years B.P.to 2800 years B.P., descended from 2800 years B.P.to 2200 years B.P., rose from 2200 years B.P.to 900 years B.P. and descended slightly from 900 years B.P. to 600 years B.P. Each one included several shifts. The sea level change was in accord with the verticalchange of diatoms in core samples,the climate change reflected by sporo-pollen analyses of samples, the deposit periods of sand bar and the changes of ancientculture relics sites.
