Abstract The microtremor noise data of 12 stations in western Inner Mongolia are used to calculate site response based on Nakamura noise spectral ratio method. The site responses of stations are classified into 3 categories according to the shape of site response curves. Site response is affected by topography, structure, base condition and so on. Comparing noise spectral ratio method with Moya method shows that the curve shapes of these two methods are basically consistent, only a few stations are significantly different. The results show most stations in western Inner Mongolia are in a good site platform situation, and site response curves are relatively flat, without obvious frequency amplification points.
