Qc is one of the important physical parameters to describe the attenuation of seismic waves underground. It can reflect the intensity of seismic activities and the degree of inhomogeneity of the underground media in a local area. In this work, the seismic records of 1 252 M ＞ 2.0 earthquakes with epicenter distance less than 100 km received by five fixed digital seismic stations in the focal area of the 1932 Changma earthquake and its adjacent areas from 2008 to 2020 were selected to calculate and analyze the attenuation characteristics of code wave in this area using Aki's single scattering model. Results show that: (1) the attenuation relationship between frequency f and Qc values with window lengths of 20, 30, and 40 s are Qc=^(71.76±8)f^(1.10±0.04), Qc=^{(103.83±17)f(1.04±0.06)}, and Qc=^(120.77±22)f^(1.00±0.06), respectively. (2) The spatial distribution diagram of Qc values plotted by Kriging interpolation indicates a correlation between the distribution of Qc values and the geologic structure and seismic activity in the focal area of the Changma earthquake and its adjacent areas. (3) The low Q₀ and high η in the study area are consistent with the strong tectonic activity in the region.
