| Abstract: | On the basis of the repeated observational data of seismic gravity network since 1990s in Qilianshan-Hexi area,the changes of local geoid in different time scale are calculated with Bruns formula and approximately solution of Stokes' integral those are usually used for getting the difference of geoid from gravity field model.The variation of local geoid and the relation to geologic tectonic and seismicity are researched.The conclusions are that the general shape of local geoid variation in Qilianshan-Hexi a... |
