In order to evaluate the operational environment adaptability and comprehensive support capability of lidar in civil airport, experimental data was monitored in a typical plateau airport by using a wind lidar which is made in China. By considering the factors such as historical weather data in the same place, the weather condition of sunny, cloudy, overcast, fog and rainy days, the lidar's wind data was analyzed, and then the typical wind feature in a plateau airport was revealed. The comprehensive support capability of a wind lidar was also tested at the same time. The results show that, lidar' s performance of catching wind field is different under different weather condition. In sunny, cloudy, and overcast days, its performance is better, and its horizontal and vertical sounding range is up to 6623m and 2895m, respectively. Moreover, the lidar can accurately discover the wind field's typical feature that is changeable in timing and spacing. This study provides a reference for the application of radar in civil aviation.
