Based on the observation data obtained during the survey and selection process of seismic stations in the Qinghai-Xizang Plateau Earthquake Monitoring Capability Improvement project,the RMS value and noise power spectral density of 6 selected stations in northwest Tibet were calculated,and the ambient noise level and base grade of each station were evaluated. The research show that the noise level of 5 sites reaches Class Ⅰ standard and 1 site reaches Class Ⅱ. The field survey work of the newly built monitoring station of the Earthquake Agency of Xizang Autonomous Region has been completed at a high level,which can provide data support for the formal construction.
