摘　　要：选取山西地震台网2021年9月—2023年3月的实际震例,以中国地震台网正式编目结果为依据,将预警台站编目定位结果和正式编目结果的发震时刻、震中位置、震级偏差做对比,梳理地震基本参数的偏差范围,探讨预警台站地震定位精度。总体来说,预警台站定位的地震基本参数数据结果整体可靠,偏差较小。In this paper,the actual earthquake cases of Shanxi seismic network from September 2021 to March 2023 are selected.Based on the official cataloging results of China Earthquake Network,the earthquake onset time,epicenter location and magnitude deviation of the cataloging results of early warning stations are compared with the official cataloging results,and the deviation range of basic earthquake parameters is sorted out to discuss the earthquake positioning accuracy of the early warning stations.In general,the data results of earthquake basic parameters located by the early warning stations are reliable and the deviation is small.
