为提高机场辐射范围测算的合理性,建立引入机场间竞争因素的改进Wilson模型。依据建立的模型,以长江三角洲区域机场为实例,对在不同市场环境下的机场,进行辐射范围研究,结果表明:(1)长三角地区具有较强辐射能力的机场共5个;(2)在竞争型市场环境下,除宁波机场外,各机场的辐射范围比凝聚型市场环境下的辐射范围要大;(3)在竞争型市场环境下,上海虹桥机场优势较明显,在凝聚型市场环境下,南京禄口机场优势较明显。研究结果为未来区域机场布局和机场航线规划提供了一种理论分析方法。
In order to improve the rationality of the calculation of the radiation field in the airport, an improved Wilson model is proposed to introduce the competition among airports. According to the established model, the Yangtze River Delta Regional Airport is taken as an example to study the radiation range of the airports in different market environments. The results show that: (1) there are 5 airports in the Yangtze River Delta with strong radiation capacity; (2) In a competitive market environment, except for Ningbo Airport, the radiation range of each airport is larger than that of a cohesive market environment. (3) In the competitive market environment, Shanghai Hongqiao Airport has more obvious advantages. In the cohesive market Environment, Nanjing Lukou airport more obvious advantages. The results provide a theoretical analysis method for airport layout and airport route planning in the future.
