Abstract:: The CGRF2010(Chinese reference geomagnetic field on 2010 epoch)was used in this paper to calculate the lithospheric magnetic field(ΔX,ΔY and ΔZ components)of Sichuan-Yunnan region.And the lithospheric magnetic field was mapped.We put all 8 strong earthquakes epicenters with M≥7 from 1970 on the lithospheric magnetic field map,and analyze the general characteristic of the distribution.And magnitude of the lithospheric magnetic field around the 8 strong earthquakes was counted and analyzed.The results indicated that the block boundaries of the Sichuan-Yunnan region matched the lithospheric magnetic field distribution very well,and boundaries between positive area and negative area mostly distribute along local faults.The epicenters of the strong earthquakes also distributed along the boundaries between positive area and negative area,and mostly in lithospheric magnetic field negative area.
