Abstract: In recent years, the continuous growth of plateau airport and flight transportation volume has led to further aggrava鄄 tion of aviation noise problems at plateau airport. In order to scientifically and effectively assess the impact of plateau airport noise on the surrounding environment, a noise calculation model of departure route suitable for plateau airport is established based on the environmental correction value of noise data caused by the difference between specific environmental conditions and standard atmospheric conditions at plateau airport. At the same time, combined with the noise data at plateau airport and profile information of departure route, the spatial distribu鄄 tion of noise around the departure route is established. The experimental results show that the noise value and af鄄 fected area after the correction based on the plateau airport environment have decreased compared with those be鄄 fore the correction, and according to the three-dimensional spatial model of noise, it can be determined that the al鄄 titude range of the plateau airport departure routes that generate a sound pressure level of 70 dB or above on the ground is between 0 m and 2 000 m. This study contributes to the noise calculation of departure route at plateau airport and provides support for departure route optimization studies.
