摘　　要：作为我国地震监测工作乃至防震减灾事业的核心基础,中国测震台网为地震监测预报和地震科学研究提供基础数据。站点参数包括站点经纬度信息和站点仪器信息。站点参数准确性,决定观测数据的可靠性和可用性,影响防震减灾工作和地震科学研究的效能。本文聚焦目前在网运行的全国测震台网1182个站点,对其参数信息进行准确性校核,同时以仪器类型为索引,整理产出此站点的观测系统参数。在此基础上,对国家测震台网中心建立站点参数数据库进行站点元数据管理的最新进展进行介绍。As the core foundation of China’s earthquake monitoring and even earthquake prevention and disaster reduction,China Seismic Network provides basic data for earthquake monitoring and prediction and earthquake scientific research.Station parameters include longitude and latitude information and instrument information.Whether the station parameters are accurate or not determines the reliability and availability of the observation data,and affects the effectiveness of earthquake prevention and disaster reduction and earthquake scientific research.In this paper,we focus on 1182 stations of the National Seismic Network currently in operation,check the accuracy of their parameter information,and sort out and output the observation system parameters of the stations by taking the instrument type as the index.On this basis,the latest progress in the establishment of the station parameter database and the management of station metadata by the National Seismic Network Center is introduced.
