The seismic anisotropy characteristics of different tectonic scales and different depths are summarized through the analysis of body wave and surface wave data based on the existing seismic anisotropy results in the Sichuan-Yunnan area. We introduce the characteristics of medium anisotropy by comparing different methods. Then we analyze the continuity and coupling of crust and mantle. The difference of the seismic anisotropy between the crust and mantle can indicate various deformation mechanisms. Therefore,we propose that the seismic anisotropy in the crust and mantle of the Sichuan-Yunnan area should be studied more quantitatively and synthetically both in theory and high density data process.
