广西区域测震台网监测能力评定

Evaluation on monitor capacity of seismic station network in Guangxi area

作者收集和整理了广西区域测震台网的资料,查阅了广西台网的观测报告,确定了不同类型模拟观测仪器的放大倍数、数字化地震仪与有效监测距离的关系,从而确定了单台的监测范围。凡4个以上的台站同时能监测到的地区则为有效监测区。分1980年以前(初创时期)、1986年以前、1993年("九五"改造前期)和2007年"十五"改造以后4个时期分别计算广西测震台网监测能力。由此了解广西区域测震台网的发展概况和监测能力不断增强的过程。

After collecting and analyzing the data of seismic station network of Guangxi area, the author identifies the unique magnification factor of distinguish analogy seismometers referring to the observation report, and also decides the relationships between digital seismometers and efficient monitoring distance. As a result, the monitor range of one single device is found. It is also determined that the effective monitor area is where can be monitored simul- taneously by four or more stations. In order to survey the gross progress of station network development in Guangxi area and the improvement of its monitor capacity, the author evalu- ates the monitor capacity of seismic station networks in four main time periods： before 1980 （founding period）, from 1980 to 1986, the year of 1993（early stage of transformation of the ninth-five year plan）, and after the reform of the tenth-five year plan in 2007.
