20111381 Geng Tao(Xi’an Center of Geological Survey of CGS,Xi’an 710054,China);Liu Kuanhou Application of Accurate Inspection of CQG2000 Quasi-Geoid Model to Regional Gravity Survey in Qinghai-Tibetan Plateau(Northwestern Geology,ISSN1009-6248,CN61-1149/P,43(2),2010,p.1-7,1 illus.,2 tables,4 refs.)Key words:gravity exploration,Global Positioning System,Qinghai-Tibetan Plateau During regional gravity survey,accuracy of orthometric height may affect the accuracy of gravity survey directly.The field test in Qinghai-Tibetan Plateau show that the accuracy of CQG2000 quasi-geoid model can satisfy the accuracy of orthometric height during the 1∶200 000 regional gravity survey.Based on the test,the authors summarize the method how the accuracy of height
