%X Dynamic gravity field variations during the period from 2000 to 2007 in China mainland are decomposed after the method of multi-scale decomposition of wavelet transform.The dynamic gravity field variations of the different-scale wavelet and the following results are drawn: 1) The first-order wavelet details are independent of tectonic activities basically.2)The second-order wavelet details well reflect the uplift of Tibetan Plateau and the preparation of Wenchuan Ms8.0 earthquake.3)The third-order wavelet details well give information about larger scale tectonic activities,such as uplift and eastward mass flow of Tibetan Plateau,Kunlun earthquake and Wenchuan earthquake.4)The third-order wavelet approximations well give information about large-scale tectonic activities,such as the collision of India plate with Tibetan Plateau,the subduction of Pacific plate to Eurasian plate and the movement tendency of north China block.
