基于GIS的山地丘陵地区通用机场选址研究

Research on General Airport Site Selection in Mountainous and Hilly Areas Based on GIS

加大通用机场建设将是未来几年的必然趋势,其场址的选择直接影响机场的安全高效运行。而在通用机场的规划建设过程中,山地丘陵地区的选址比地势平坦地区难度更大、局限更多。为此,从交通条件、建设条件、运行条件3个方面出发构建山地丘陵地区通用机场选址指标体系,利用模糊层次分析法对选址指标进行定量化评价。在此基础上,基于GIS(地理信息系统)建立山地丘陵地区通用机场选址决策模型,用于获得通用机场选址因子评价可视化结果,以此揭示通用机场选址的适宜性空间分布,为相关决策提供可靠的量化依据。以华东某通用机场选址为例验证模型和方法的可用性。

The expansion of general aviation airport construction will be an inevitable trend in the coming years,and the selection of the airport’s site directly influences its safe and efficient operation.In the planning and construction process of general aviation airports,the selection of sites in mountainous and hilly areas poses greater challenges and limitations compared to flat terrain.A site selection index system for general aviation airports in mountainous and hilly areas is constructed based on three aspects:transportation conditions,construction conditions,and operational conditions.The fuzzy analytic hierarchy process is utilized to quantitatively evaluate site selection criteria.Building upon this,a decision model for general aviation airport site selection in mountainous and hilly areas is established using GIS(geographic information system)to obtain visualized results of the evaluation of airport site selection factors.It reveals the suitability of spatial distribution for general aviation airport site selection,providing a reliable quantitative basis for relevant decision-making.The model and methodology’s usability is validated using the example of site selection for a general aviation airport in the east China region.
