Based on the observation data of the earth microtremor in Quanzhou area, this paper discusses some important technical problems about observation and analysis of the earth microtremor, and studies the law of microtremor spectrum feature and the relationship between it and relative parameters in the site. Moreover, this paper also discusses the action of pulse predominant period in the site evaluation, the relationship between the period and shear wave velocities of soil layers and the concerned problems.
