应用噪声谱比法，收集了福建台网观测台站记录的地脉动噪声数据，计算分析了85个观测台站的场地响应。根据场地响应曲线形态将福建台网观测台站分为4类，并简要分析了影响台站场地响应结果的因素。计算结果表明，福建台网观测台站台基情况普遍较好，在台站观测频带内场地响应曲线平坦，大部分台站均没有明显的频率放大点。本文采用 H／V 谱比法与 Moya 方法所获得的37个台站的场地响应结果基本一致，仅有少数台站存在较大差异。应用场地响应分析结果，结合计算震级时所量取的周期，对福建台网观测台站的单台震级校正值进行了估计，并与统计方法获得的单台震级校正值进行了比对。结果表明，两种方法获得的台站震级校正值存在一定的相关性，但由于考虑的影响因素不同，具体的台站震级校正值尚存在差别。

Based on the Nakamura H/V spectral ratio (NHVR)method,the site response of 85 seismic monitoring stations in Fujian region were analyzed by using microtremors noise data recorded by the stations of Fujian teleseismic network in this paper.Then,we divided the stations into four groups according to the shape of site response curves,and briefly analyzed the factors resulting in different site response results.As a result of good site situation of platform, most of the stations of Fujian teleseismic network has a flat site response curve without obvious frequency amplification point.In addition,the site response obtained by NHVR method in this paper is basically consistent with that of 37 seismic stations calculated by Moya method,except for a few of stations.With reference to the periods during the magnitude calculation,we obtained the magnitude correction value of each seismic station of Fujian network,and com-pared them with those by statistical method.The results indicate that the two kinds of specific magnitude correction values have a certain correlation,but due to different factors considered during the analysis,there are also some differ-ences.
