我国地震地下流体观测台网调整与优化方案探讨

摘要

本文首先简要介绍了我国地震地下流体观测台网的现状，然后针对其存在的主要问题提出了调整与优化的建议：①调整布局，重点加强我国中西部地区（105°E 以西）的监测；②扩大规模，观测井（泉）数要达到1000个左右；③全面提高观测井质量，淘汰不符合规范要求的观测井（泉），改造不完全符合规范要求的观测井，新建一批完全符合规范的观测井；④优化观测项目的组合，大力发展观测井（泉）水流量观测，强化以 H2、He、CO2等为主测项的断层带土壤气观测，建立断层带土壤气观测网；⑤优化现有的观测模式，开展平面上的台阵式观测与垂向的多层次立体化观测；⑥完善与提升现有数字化观测技术水平。%The current situation of the earthquake subsurface fluid monitoring network in China is briefly introduced.And then,some suggestion on adjust-ment and optimization of the network are proposed.① Change the layout of the existing monitoring network so as to focus on the middle-western China,partic-ularly to the west of 105°E.② Increase the number of monitoring wells or springs up to approximately 1 000.③ Improve the quality of monitoring net-work,eliminate and transform those wells or springs that do not meet for the standards and requirements at all.④ Optimize the monitoring items,focus on the monitoring of the wells or springs flows,the soil vapor in the vicinity of faults (main parameters are H2 ,He,CO2 ),and construct a soil vapor net-work.⑤ Optimize the existing monitoring modes,establish the plane array observation and vertical multi-level three-dimensional observation.⑥ Improve the existing digital monitoring technology.
