摘　　要：本文利用中国地震台网记录的宽频带波形资料,采用近震全波形反演方法得到2023年3月1日—7月31日发生在中国内地地区的M≥4.0共30次地震震源机制解。结果显示逆断型7次,走滑型14次,正断型8次,未知型1次。In this paper,the regional full waveform inversion using the broadband waveforms recorded by China Seismic Network were conducted,and the focal mechanism solutions of the 30 earthquakes with M≥4.0 occurred in the mainland of China during March to July 2023 were obtained.The types of these focal mechanism solutions show 7 reverse faulting,14 strike-slip faulting,8 normal faulting and 1 odd earthquake.
