The invention relates to an urban low-altitude airway safety assessment method and system considering biological activities, and the method comprises the steps: constructing a spatial three-dimensional grid based on a two-dimensional basic grid of ground space division, and constructing an index structure; calculating feature information of the organisms appearing in each three-dimensional grid in the low-altitude airspace in different scenes according to the space-time trajectory information of the activities of the organisms in the low-altitude airspace; acquiring an air route of the aircraft in the low-altitude airspace, and calculating relative feature information between the organisms and the aircraft in the three-dimensional grid; performing quantitative analysis and calculation on the risk of collision in the three-dimensional grid on the air route to obtain risk index information of the air route; and determining a safety risk assessment result of the low-altitude air route. According to the method, comprehensive, fine, dynamic and systematic safety risk quantitative evaluation is carried out on the urban low-altitude air route, the safety influence of biological activities in different periods on the urban low-altitude air route can be quantified, and the method can be used for low-altitude infrastructure site selection, low-altitude air route planning and the like.
