摘　　要：根据中国测震台网现有台站布局和实际记录的背景噪声波形资料,通过近震震级公式评估测震台网的理论地震监测能力,并与地震测震台网实际地震监测能力进行对比。结果显示,理论与实际地震监测能力基本相符,即中国中部地区可监测震级下限较低,台站分布稀疏的青藏高原西部、新疆东南部和内蒙古北部边界地区等可监测震级下限较高。In this paper,the theoretical seismic monitoring capability of the China Seismic Network is calculated by using the background noise data of 1155 seismic stations in China.The theoretical values are tested.The actual monitoring capability of the China Seismic Network is calculated by using the formal seismic observation report provided by China Earthquake Networks Center.The results show that the theoretical monitoring capability is consistent with the actual monitoring capability.

关 键 词：地震监测能力 理论地震监测能力 实际地震监测能力 中国测震台网
