Abstract：By use of the regional leveling and GPS observations in SichuanYunnan area during 1994-2006, aided by the negative dislocation model for the elastic block boundaries, combining with the total characteristics of deformation crossfault, the recent status and intensity of strain accumulation of tectonic blocks and their boundary faults in SichuanYunnan area are studied. The results show that recent status of tectonic stress in SichuanYunnan area manifes itself in energy accumulation mainly.The strain energy accumulation appears obviously in the Anninghe fault and the regions where it meets Zemuhe fault and Xianshuihe fault, the Yanyuan-Lijiang block and its margins, it may be the medium and shortterm precursors of some coming earthquakes.
