中文摘要：
采用Nakamura方法，利用2007年6月3日宁洱地震强震动记录S波资料和脉动观测资料，计算了宁洱震区一些强震动台的场地响应。结果表明，当台站场地为基岩或覆盖层较薄时，由脉动数据和S波数据分别计算的谱比曲线一致性很好。当覆盖层大于35m的时候，两者的谱比值有差异，即用S波计算的场地放大响应要明显大于用脉动计算的场地响应。
英文摘要：
In this paper, we calculate the strong motion site responses by the Nakamura method based on the pre-seismic microtremor and S wave data recorded during Ning＇er earthquake on 3 June 2007. The site response spectra of microtremor and S wave are consistent in general for basement rock site or thin-overburden site. However, for thick-overburden site over 35 meters, both spectral ratio curves have obvious differences, which means that the site response spectra calculated by ground micro-tremor is much bigger than that calculated by S wave.
