According to the ground micro-tremor test, we obtained ground micro-tremor data recorded by 45 measur- ing points in surrounding area of Anning River and Qionghai Lake, and processed the data by spectral analysis. We analyzed and summarized the characteristic of spectral curve of ground micro-tremor, obtained spectrum characteristics of ground micro-tremor, and gave the advised values of predominant period of site ground micro- tremor in study area according to different site conditions. The results not only provided the site background in- formation and analysis basis in the planning of Xichang seismic disaster prevention and mitigation, but also pro- vided meaningful references for the engineering site selection, site type classification and structural seismic de- sign in Xichang in future.
