The invention discloses a virtual-real fusion air route planning algorithm performance evaluation method. The method comprises the following steps: step 1, generating a ship target; 2, setting a navigation parameter, a collision avoidance rule and an efficiency evaluation benchmark; step 3, navigation simulation; step 4, calculating the minimum linear distance with each obstacle target; 5, calculating an average deviation value of the air route; step 6, calculating a collision risk average deviation value; 7, calculating a navigation time deviation value; and step 8, evaluating the performance of the air route planning algorithm. According to the method, in a laboratory environment, actual test data such as an electronic chart, a radar target, an AIS target and the like and virtually constructed ship target data are combined, the efficiency of a route planning algorithm is judged through a virtual-real fusion test evaluation method, the safety, the timeliness and the stability of the route planning algorithm
