Based on the sounding date from captive boatover the hinterland ofTaklimakanDesert inwinterof2008, the atmosphere stability therewas studied elementarily using three differencemethodswhich areTemperature differencemethod,Temperature differenceW ind speedmethod andRichardson numbermethod. Results showed: (1)The diurnal change of the atmosphere stabilitywas obvious in Tazhong, atnight the state of the atmosphere changed from stability to neutral then instabilitywith the height increase, and the surface layerwas instable due to the impactof the solar radiation in daytime; (2)The atmosphere stability has significantly stratificationwith the height increase, the stable and the instable layer appeared alternately; (3)The results calculated by the above threemethodswere different, which reflected that the atmosphere stabilitywas influenced by temperature,wind and turbulence.
