主　　题：Tibetan plateau Gravity datum Gravity network adjustment 

摘      要：A new gravity base network in the south of the Tibetan Plateau was established with a FG5X absolute gravimeter and three CG-6 *** gravity base network consists of 10 absolute gravity points and 17 relative gravity *** of the absolute data,pre-processing of the relative data and gravity network adjustment model are briefly *** a constrained weighted least squares,the combined adjustment of absolute and relative gravity measurements results in the gravity values with a precision of about±4.1μGal.
