福建地球物理台网数据跟踪分析探讨

Discussion on Data Tracking Analysis of Fujian Geophysical Network

对福建地区不同观测手段仪器的数据进行跟踪分析,总结不同学科仪器观测曲线的变化趋势和观测效能,结果表明:(1)福建地区73.68%的形变观测曲线具有清晰年变动态;(2)重力仪映震效能好,同震响应与地震强度、震中距呈正相关关系;(3)地磁观测年变比较有规律且有一定周期性;(4)福建地区水温观测质量较高,水位受降雨影响不同台站年变幅度不同。

By tracking and analyzing the data of different observation instruments in Fujian,we summarized the change trend and observation efficiency of instrument observation curves in different disciplines:(1)73.68%of the deformation observation curves in Fujian had clear annual variation;(2)The co seismic response of gravimeter was positively correlated with earthquake intensity and epicentral distance;(3)The annual variation of geomagnetic observation was regular and periodic;(4)The observation quality of water temperature in Fujian was high,and the annual variation range of water level was different with different stations affected by rainfall.
