摘　　要：速报工作的关键是在最短的时间内,准确的报出地震三要素。经过对所选的速报地震进行重新定位并与编目结果对比分析,发现在速报过程中,在以包围震中为原则的前提下,一般网内与网缘地震所选台数在7至9个台,网外地震所选台数在10至15个台,这样的速报结果与辽宁地震目录结果最为接近。通过速报与编目定位结果的对比,分析在不影响地震速报质量的前提下,使用最佳数量的台站定位出辽宁北部、辽宁中部以及辽宁南部地震多发区域与地震编目最接近的结果。The key of earthquake quick-report in the shortest possible time, accurately reported the three elements of earthquake. Repositioning selected quick-report seismic and comparing analysis of the catalogue results. We found the number of stations in earthquake location 7-9 stations and the number of stations outside in earthquake location 10-15 stations, the results are better. By contrast with the cataloging positioning result of the positioning of the northern part of Liaoning Province,central Liaoning Province and southern Liaoning earthquake-prone area, we get the closest results with earthquake catalog.
