通用航空应急救援点选址布局优化研究

为了使通用航空应急救援与城市综合应急救援体系的快速发展保持一致，根据城市航空应急救援的需要，提出了通用航空应急救援点的选址布局方法。首先，基于层次分析法构建通用航空应急救援点选址布局的影响因素分析模型；其次，使用ArcGIS软件对影响选址因素中可矢量化的指标进行空间分析，得到符合要求的预选址区域；然后，构建通用航空应急救援点选址布局数学模型，即加权距离总和最小化以及优先选取权重较高的救援候选点，并通过Lingo软件求解；最后，通过案例进行可行性分析，验证模型和方法的合理性。结果表明，该模型和方法具有较高的准确性和较好的适用性。该方法的提出为通用航空应急救援点的选址布局提供了理论依据，具有一定的参考意义。

Research on the optimization of location and layout of general aviation emergency rescue points

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.
