Appling the Shakemap site correction methods of U. S. for the rapid prediction of ground motion intensity and seismic intensity in Yunnan, we analyzed Shakemap site correction method and its main points, and applied it to the comparison and analysis of typical regions in Yunnan and the actual site conditions, and discussed the relevant parameters problems of it. We should improve the relevant parameters of Shakemap site correction meth- od in Yunnan. Firstly, we supplied the classification of site conditions only based on topographic slope single in- dicator, which should be considered the correlation between V~~ and multi-index factors （ such as the near-surface geological conditions, elevation, the distance from the river etc. ） . At the same time, we must consider the impact of local site conditions on ground motion in the actual site conditions and modified the amplification of lo- cal site conditions on ground motion from the soft soil of basin, the geological structure and the local sand lique- faction sites etc.. Basing on the theoretical calculation results, combining with modifying actual site conditions, we could improve the precision of predicted results by double correction of theoretical and practical, which could provide useful information and help for emergency decision after the earthquake.
