In this paper, we analyzed 42 three-component acceleration data from the M6.4 earthquake occurred on January 19, 2020 in Jiashi country, Xinjiang, to study the characteristic of the amplitude, duration and response spectrum of the strong motion records. The results show that the maximum peak of acceleration value is 633.3cm/s², and the seismic intensity of the instrument is Ⅸ degrees, the ratio of acceleration peak to vertical peak value is between 0 and 4, the peak value of acceleration of this earthquake is basically within the range of Yu13 long axis error of ground motion attenuation relationship, which is higher than Zhang's predicted value. The excellent period of horizontal acceleration response spectrum is mainly concentrated in 0~0.5 seconds, and the vertical direction is concentrated in 0~0.2 seconds, The horizontal response spectrum of 65XKR station is higher than Ⅷ degrees rare earthquake design response spectrum, the value is 0.48 seconds, the vertical response spectrum is higher than Ⅷ degrees rare earthquake design response spectrum, and the peak value is in the high frequency band.
