摘要: 为揭示机场群空间演化的差异化特征与内在驱动机制,推动机场群协同发展,优化航空网络布局,本文以京津冀和成渝两大机场群为研究对象,围绕胡焕庸线东西两侧航空资源分布特征,从多尺度视角系统分析其空间异质性。通过构建覆盖能力指数、覆盖异质性指数、空间影响力模型、空间影响力异质性指数、航线重叠系数和航线异质性指数等量化指标,综合对比不同辐射半径下两大机场群的连通结构、服务覆盖和网络差异。研究发现:1500km辐射半径是机场群覆盖能力与空间异质性变化的转折阈值;两大机场群均呈现“东强西弱”的共性特征,且成渝机场群的东西差距更为显著;京津冀与成渝机场群东侧综合影响力占比分别为77.73%与93.55%,凸显区域航空资源集聚程度的差异;重叠航线沿胡焕庸线集中分布,西北侧航线结构异质性高而密度低,东南侧则呈现“高密度、低差异”的结构特征;权重系数灵敏度分析表明,模型结果具有较好的稳定性和可靠性。研究揭示我国机场群空间格局与区域经济发展之间的耦合机制,为优化航空资源配置,推动机场群协同和东西部均衡发展提供了理论依据和决策参考。

Abstract: To reveal the differential characteristics and intrinsic driving mechanisms of the spatial evolution of airport clusters, promote their coordinated development, and optimize air network layout, this study takes the Beijing-Tianjin-Hebei (BTH) and Chengdu-Chongqing (CCQ) airport clusters as research objects. Focusing on the distribution characteristics of aviation resources on both sides of the Hu Huanyong Line, it systematically analyzes the spatial heterogeneity from a multi-scale perspective. By constructing the quantitative indicators including coverage capacity index, coverage heterogeneity index, spatial influence model, spatial influence heterogeneity index, route overlap coefficient, and route heterogeneity index, the study comprehensively compares the connectivity structure, service coverage, and network differences of the two airport clusters under different radiation radii. The results show that: (1) the 1 500 kilometers radiation radius is a turning threshold for changes in coverage capacity and spatial heterogeneity of airport clusters; (2) both of two airport clusters exhibit a common feature of "stronger in the east and weaker in the west", and the east-west gap is more significant in the CCQ. (3) the comprehensive influence proportions of the eastern sides of the BTH and CCQ are 77.73% and 93.55% respectively, which highlights differences in the agglomeration degree of regional aviation resources; (4) overlapping routes are concentrated along the Hu Huanyong Line, with high structural heterogeneity but low density on the northwest side, and "high density and low difference" on the southeast side; (5) the sensitivity analysis of weight coefficients indicates that the model results have good stability and reliability. This study reveals the coupling mechanism between the spatial pattern of Chinese airport clusters and regional economic development, providing the theoretical basis and decision-making reference for optimizing aviation resource allocation, promoting airport group coordination, and balancing the development between the east and west.
