【摘要】 地震地球化学离子、气体成分等其它观测项目是地震地下流体观测网的重要组成部分,在地震监测预报工作中发挥了重要作用。本文对观测项目的规模、观测数据质量和数据预报应用3方面进行分析,梳理了地球化学离子、气体成分等观测项目的背景变化规律;指出近年来观测规模急剧缩小、观测数据评价体系不完善、台网管理缺失严重等现状;并提出需清理观测项目、完善仪器更新机制、加强台网管理和建立人员培训机制等建议。更多还原

【Abstract】 Ion, gas and other items of groundwater observation are important parts of seismic underground fluid observation network, which play the important roles in earthquake monitoring and prediction. In this article we review the three aspects of the scale, the quality of observation data and the application of earthquake monitoring and prediction in China. The background dynamic changes of ion, gas and other items is also analyzed. Our results show some problems in groundwater observation in recent years such as insufficient projects, lack of data quality evaluation system and lack of effective management of network. In the future, we need to reorganize the observation items better, to improve the instrument renewal mechanism, to strengthen the management of the networks, and to set up personnel training mechanism.更多还原
