| description | The invention belongs to the field of flight situation evaluation of air traffics, and discloses a low-altitude flight situation safety evaluation method which can be used to evaluate the flight safety state and change trend of dense aircrafts in specific space-time of low altitude, and provide technical support for low-altitude flight monitoring, space domain division and use. The method comprises that low-altitude operation environment characteristics and flight situation real-time data are analyzed; key low-altitude flight situation safety evaluation indexes and a calculation method thereof are established, and the indexes include the flight conflict frequency, the average flight conflict duration, the conflict release behavior ratio, the gathering situation approaching degree and the collision risk intensity; and the correlation and difference among the key indexes are analyzed to provide a comprehensive fuzzy clustering evaluation method of the low-altitude flight situation safety.
