摘　　要：利用中国地震台网1985—2001年面波资料,基于该台网使用的面波震级计算公式,计算64个地震台站面波震级台基校正值,结果表明:地震台站受所在地区地壳结构、近地表岩石性质、土壤疏松程度、地形等因素影响,大部分台站校正值在±0.2之内,最大校正值为-0.31。On the basis of the formula of surface wave magnitude and the data of surface wave recorded by Chinese seismograph network during 1985 to 2001, the correction values of station basement for surface wave magnitude of 64 stations were calculated. The results showed that, as the influence of crustal structure, properties of rocks near surface, soil porosity, topography and other factors of seismologic stations in different regions, the correction values in most of seismic stations are smaller than ± 0.2, and the maximum is -0.31.
