Abstract In order to study the gravity anomaly correction affected by the different density of gravity stations in the uneven terrain when the precise leveling is performed, the gravity anomaly corrections are calculated in Hexi area ,where the leveling circuit have enough observaions.Having compared the gravity anomaly corrections with that calculated from Bouguer anomalies map, the results show that the correction value is affected by the distribution and density of the gravity sites. When they are good, the quality of the precise leveling will be improved.
Key words ：
