Abstract The results of simulation and ground measurements show that there is obvious nonlinenar variation in vertical gradient of gravity from the ground surface to a height of 80 cm and 130 cm，the amount is more than 002×10-8ms-2/cm，and the variation of gradient increscent with the changes of elevation.Therefore，the difference caused by height has to be paid attention in gravity measuring with FG5 and A10 absolute gravitymeter
Key words ：
