摘　　要：国家地震烈度速报与预警项目已经在全国范围内正式启动,预警工程宁夏子项目在宁夏境内亦全面展开,宁夏回族自治区地震局于2018—2019年已经全面完成预警基准测震台站的勘选工作。截至目前,我局预警工程宁夏子项目基建工作也基本完成。此次,利用地震近震计算公式及预警工程勘选期间所记录到的台基噪声原始数据。通过分析和计算,对宁夏回族自治区预警工程全面建设完成和投入使用之后的区域台网监测能力进行分析和评估,结果表明,相较于预警工程之前,宁夏区域台网基准台站数量大幅提升,宁夏区域台网监测能力也将大幅提升,宁夏境内基本实现1.0≤M<1.5震级监测能力的全覆盖。The national earthquake intensity quick reporting and warning project has been officially launched nationlly,so has the Ningxia sub-project in the local regions been.The Earthquake Administration of Ningxia Hui Autonomous Region has completed the survey and selection of basic stations for early warning from 2018 to 2019.And the construction of the Ningxia sub-project has also been nearly finished so far.Based on the calculation formula of near earthquake and the original data of noise level recorded during the survey and selection of the Ningxia sub-project,the monitoring capability of regional network was analyzed and evaluated through analysis and calculation after the construction accomplishment and operate initiating of earthquake intensity quick reporting and warning project in Ningxia Hui Autonomous Region.The results show that,compared with before the number of basic stations in Ningxia regional network has been greatly increased.The monitoring capacity will increase in the future.The magnitude monitoring capacity of 1.0≤M<1.5 will be actualized almost throughout Ningxia region.
