区域枢纽机场时刻资源的时空分布差异研究——以成都、重庆为例

以成都及重庆机场为研究对象,收集其航班时刻数据,使用波动率、对外联系；度以及自然间断点分级等方法,从时间及空间维度定量地刻画邻近区域枢纽机场间的航班时刻配置差异。研究表明：(1)区域枢纽机场均形成早晚高峰形航班波,但较大的机场在日间运行时航班架次波动性更低,起降波峰平均间隔较短,且夜间的国际航班量更大；(2)国内联系机场形成四个层级,对外联系度较大的对象均位于省级或副省级城市,且新疆和东北与内地的联系倾向于较大型机场,其层级更高；(3)国际联系机场形成三个层级,与东南亚地区对外联系度大,但较大型机场与其联系强度更高。

Analysis of Temporal-spatial Allocation Differences in Schedule Resources of Regional Hub Airports:A case study of Chengdu and Chongqing

Taking Chengdu and Chongqing airports as the research objects, we quantitatively describe the flight schedule allocation differences between adjacent regional hub airports from the temporal-spatial dimension by collecting flight schedule data and applying methods such as Volatility, External linkage degree and Natural breaks (Jenks). The results show that: (1) All regional hub airports formed morning and evening peak flight waves. Larger airports have lower daytime flight volatility, shorter average interval between taking-off and landing wave peaks and more international flights during night. (2) There formed four levels of domestic connecting airports. Objects with higher external connection degree are all located in provincial or sub-provincial cities. The connections of Xinjiang and the northeast between the mainland tend to be like larger airports, with higher levels. (3) International connecting airports fall into three levels, having a high external connection level with Southeast Asia, nevertheless the connection strength between larger airports and Southeast Asia is even higher.
