In order to analyze the performance of free space quantum communication influenced by the atmospheric turbulence which is close to the ground , the relationship between the turbulence meteorological parameters and the entanglement of quantum channel was obtained according to the Tunick model of the atmospheric turbulence. For the quantum depolarization channel and amplitude damping channel, the equation between meteorological parameters and the channel capacity was established. The effect of turbulence on the quantum channel utilization was analyzed, and the performance simulation was carried out .The simulation results show that, when the atmospheric pressure is 100 kPa, the wind speed is 2 m/s, the temperature is 25℃ and relative humidity are 0.2 and 0.6 respectively, the degree of entanglement for the quantum channel are 0.27 and 0.18, the capacity of depolarizing channel are 0.951 6 and 0.946 5, the capacity of amplitude damping channel are 0.439 0 and 0.422 7, the utilization of quantum channel are 0.42 and 0.37, respectively. The various parameters of quantum communication channel and the meteorological parameters of the atmospheric turbulence close to the ground are closely linked. The reliability of quantum communication can be improved when the parameters of quantum communication system can be adjusted adaptively based on the meteorological parameters of the atmospheric turbulence closed to the ground.
