摘　　要：系统分析了自1970年7月四川区域地震台网有记录以来长宁窗发生的M L≥3.5地震及其与四川及邻区M≥5.5中—强地震的对应关系。结果显示,根据一定的预报规则,长宁窗地震可作为判定四川及邻区是否发生M≥5.5地震的中期预测指标,该指标对四川地区M≥6地震预测效果最好。We have systematically analyzed the relationship between ML ≥ 3.5 earthquakes in Changning window and moderate-strong earthquakes in Sichuan and its adjacent area recorded by Sichuan Regional Seismic Network since Jul.,1970.The result shows that ML ≥3.5 earthquakes in Changning window can be considered as the middle-term prediction indicator whether or not M≥5.5 or M≥6 earthquakes occurred in Sichuan and its adjacent area,especially for M≥6 earthquakes in Sichuan area.
