摘　　要：通过对滇西南地区Ｍ≥５级地震前地震、前兆和环境因子变化特征的分析，发现滇西南中强震前小震频度增加、出现窗口信号地震，前兆异常数量多，气压涨落突出等特征，并以此为依据建立了滇西南地区Ｍ≥５级地震的预报方案。The authors have analysed the seismicity 、precursors and environment factor before M≥5 earthquakes,and found the characteristics of small earthquake frequence higher before medium strong earthquake、window signal earthquake、many precursory anomalies and gas pressure changed obviously.According to these,they proposed the prediction version of M≥5 earthquakes in the study area.
