本文简略地回顾了广东省测震台网的发展过程。根据吴开统提出的测震台网监测能力的计算方法,对目前台网的实际监测能力进行了计算。计算结果表明,台网能有效地监测省内发生的M_L≥2.5级地震.最后,还对如何进一步提高台网的监测能力提出了一些建议. This article briefly reviews the development of the seismograph network in Guangdong Province. According to the calculation method of seismograph network monitoring capability proposed by Wu Kai-tao, the actual monitoring ability of the current network is calculated. The calculation results show that the network can effectively monitor M_L≥2.5 earthquakes in the province.Finally, some suggestions are put forward on how to further improve the monitoring ability of the network.
