Abstract: In order to maintain consistency between the general aviation emergency rescue and the rapid development of the urban comprehensive emergency rescue system, the location and layout method of general aviation emergency rescue points is proposed according to the need of urban aviation emergency rescue. Firstly, based on the analytic hierarchy process, an analysis model of the factors affecting the location of general aviation emergency rescue points was constructed. Secondly, make spatial analysis about the vectorizable indicators of the factors affecting location with ArcGIS software, and obtain the pre-selected location area that meets the requirements. Then, a mathematical model of the location and layout of general aviation emergency rescue points is constructed, that is, the total weighted distance is minimized and the rescue candidate points with higher weights are selected firstly, and the solution was solved by Lingo software. Finally, a feasibility analysis was carried out through a case study, which verified the rationality of the model and method, and the results showed that the model and method have higher accuracy and better applicability. It provides a theoretical basis for the location and layout of general aviation emergency rescue points, and has a certain reference significance.
