摘　　要：关于震源深度误差问题有许多讨论,但一直也没有很好的统一的解决办法。结合目前的实际,对于区域台网记录到的浅源近震,多数是采用JOPENS-MSDP人机交互处理软件中的单纯型定位方法进行定位,直达波是参与定位的主体。本文通过对甘肃台网记录到的71个浅源近震进行分析,得到甘肃地区震中距与震源深度的比值和定位误差之间的统计关系。People always studied the error regular of focal depth, but it is not solved. According to the reality, people located the focal depth by using of the JOPENS-MSDP interactive software based on direct seismic wave phase. The authors get the formula that the location error and the specific value of the epicentral distance and focal depth by analyzing 71 shallow focus earthquake records of the Gansu Regional Earthquake Network.
