The important nodes in the air route network have an important impact on the safe and orderly operation of the airspace. This paper proposes an improved Technique for Order Preference by Similarity to Ideal (TOPSIS) method. The relative entropy is introduced to solve the problem that traditional TOPSIS method cannot distinguish plumb line nodes in positive and negative ideal solutions, and combined with grey correlation to measure the distance and edge coupling degree of the curve to make the results more accurate. The results of air route network in Eastern China show that the method is more effective and realistic.
