Abstract：Based on re-calculating to the portable gravimetri c data in Guangdong area from 1988 to 1999, the evolution tendencies of the gravi ty field in the eastern and western regions of Guangdong and the Pearl River Del ta area have been analyzed.The relation between the gravitational field and the seismicity in coast area of South China has been discussed, and the earthquake p recursory information for the time-space and strength changes of the gravity fie l d in Guangdong area have been picked to provide the criterions of the gravity an omaly before earthquakes in this area.
