Azimuth-angle-based weather modification gun station surrounding operation risk evaluation method

The invention discloses a weather modification gun station surrounding operation risk evaluation method based on an azimuth angle, and the method comprises the steps: taking a gun station as an original point, and uniformly dividing a certain operation range of the gun station into a plurality of fan-shaped operation spaces; building samples in all operation spaces of a gun station are collected, and building distribution information is extracted; human activity information in all operation spaces of the gun station is extracted, and an evaluation risk unit is constructed; and calculating the ratio of the risk unit of each operation space divided by the emission azimuth angle to the total unit of each operation space, namely the risk probability of the operation space, and taking the risk probability as a quick assessment index of the surrounding risk of the cannon station. The method is suitable for regional cannon stations without relatively large cities and towns around the cannon stations and with less bu
