| Abstract: | The relative gravimetries in the western area of Yunnan Province had been performed 28 times and absolute gravimetries many times till 1996. The computation on the dynamic change of gravity field with above data is done, the determinations of the spacial and time gravity base, and of the calculation of the influences about the instrument scale changes deduction of station movements etc.are systematically discussed in this paper. According to the gravity changes before and after the Lijiang earthguake,the limit value for judgeing the gravity changes of gravimetric network in western area of yunnan province is given. |

| Keywords: | gravity change time base spacial base scale correction station movement deduction |
