摘　　要：介绍并分析了中国地震速报台网目前地震速报定位的现状、存在的问题及原因 ,并利用1 990～ 1 997年的速报定位资料 ,统计分析了中国地震速报台网测定地震震中位置的偏差、产生偏差的原因 。The current situation, the existing problem and its cause for seismic rapid locating by China Seismic Observational Network are introduced. By using the data of seismic rapid locating for six year from 1990 to 1997, the deviation of epicenters determined by China Seismic Observation is statistically analyzed, the cause of deviation is discussed, and some improving measures are proposed.
