摘　　要：宁夏固原市双井子流体观测台位于中卫市海原县甘城乡双井村,临近宁夏罗山—固原断裂带,是宁夏回族自治区地震局优质前兆地下流体观测台之一。近三十年来,宁夏固原市境内发生的多次中强震震前,宁夏双井子流体观测台均提供了明显的前兆异常地震观测数据,为当地中强震的地震预报提供了流体资料依据,但由于洪水对周边环境的破坏、观测台年久失修、设备仪器陈旧老化,故宁夏回族自治区地震局依据中国地震局相关通知,于2018年对宁夏双井子流体观测台在观测系统、观测环境、基础设施等方面进行改造及优化,以确保宁夏双井子流体观测台在今后准确高效的运行,以进一步提高宁夏区域范围内地震前兆手段在中强地震中的预报能力。Shuangjingzi fluid observation station is located in Shuangjing village,Gancheng Township,Haiyuan County,Zhongwei City,near the Luoshan Guyuan fault zone.It is one of the high-quality precur⁃sor fluid observation stations of the Seismological Bureau of Ningxia Hui Autonomous Region According to,it provides fluid data basis for earthquake prediction of local moderate and strong earthquakes.However,due to the damage of flood to the surrounding environment,the observation station is out of repair,and the equipment and instruments are aging,the Ningxia Hui Autonomous Region Seismological Bureau,accord⁃ing to the relevant notice of China Seismological Bureau,reformed and optimized the observation system,observation environment,infrastructure and other aspects of Ningxia Shuangjingzi fluid observation station in 2018 In order to ensure the accurate and efficient operation of the Shuangjingzi fluid observation station in Ningxia in the future,and further enhance the prediction ability of seismic precursor means in Ningxia re⁃gion in moderate strong earthquakes.
