针对当前省级区域测震台网在判别边界地震是否需要速报的问题，基于内蒙古自治区行政区域的边界数据，利用几何学中包络线原理，在Matlab中将内蒙古地震速报范围以包络线的形式呈现，解译Msdp地震分析软件的数据接口，实现内蒙古地震速报区域在Msdp软件中的自动确认；对比分析地震速报区域自动确认功能的结果与现阶段手动量取方式判别地震事件是否需要速报的结果，表明地震速报区域的自动确认可提高速报业务软件系统的自动化程度，简化地震速报工作的操作流程，减少速报用时，提高速报工作的准确度。

Aiming at the problem that the current method is used by provincial digital seismic network to judge whether the boundary earthquakes need rapid report or not,based on the boundary data of the administrative region of Inner Mongolia Autonomous Region,the envelop line principle in geometry is used to present the Inner Mongolia earthquake rapid reporting range in the form of envelop line in Matlab. By interpreting the data interface of Msdp seismic analysis software,the earthquake rapid reporting range of Inner Mongolia is confirmed automatically in Msdp. The results of the application of judging whether boundary earthquakes need rapid report by using intelligent earthquake rapid reporting range and the present way of manual measurement respectively shows that the automatic confirmation of earthquake rapid reporting range can improve the degree of automation of the rapid reporting business software system,simplify the operation process of earthquake rapid reporting work,reduce the time of rapid reporting work and improve the accuracy of rapid reporting work.
