| 摘 要： | 为进一步提升我国地震前兆台网的管理水平,对数字化地震前兆台网观测数据质量进行快速而科学合理的评价,在现有各学科评比办法的基础上,开展了台网数据质量评价方法研究。通过研究获得了1套包含观测数据的完整性、噪声水平、固体潮汐效应、一致性等多方面的数据质量评价指标,在此基础上,采用规范化处理与加权平均等方法建立起台网数据质量评价方法。应用分析显示,评价结果基本能够反映台网的数据质量实际状况。

| Abstract: | In order to further improve the management level of the National Earthquake Precursory Observation Networks of China,and evaluate rapidly and scientifically the quality of digital observation data on the basis of the current subject evaluation methods,the data quality evaluation method of the Earthquake Precursory Observation Networks are studied. A set of data quality evaluation index associated with data integrity,noise level,solid tidal effect,consistency and other aspects is obtained,and then the data quality evaluation method of the Earthquake Precursory Observation Networks is established with the help of standardized treatment and weighted average methods. Application results show data quality indexes of the evaluation method is relatively comprehensive and reasonable. The evaluation results are basically consistent with the actual situation of the networks data quality. The evaluation method has been used in the national regional precursory network appraisal work. The study lays a foundation for the rapid assessment and quality classification of the Earthquake Precursory Observation Networks. |
