我国民航2011年支线网络分布特点分析

Analysis of China's Regional Air Network in 2011

依托2011年我国民航航段生产数据，提出了支线航线的界定标准，进而分不同支线航线属性和不同机场两个层次，梳理总结了我国民航支线网络的分布特点，表明干支客运航线是支线航线的主要类型，年旅客运输量能否突破5～10万是干支客运航线发展的重要节点；西北、华北、西南、华东地区的支线网络主要服务所在地区，而东北、中南两个地区的支线网络主要辐射临近地区；除北上广以外，对于支线航线数量在10条以上的干线机场，其支线网络的发展应加强航线的连通性，并更加注重挖掘区域内部的运输需求。

This paper studies the regional air network （RAN） of China in 2011 in two dimensions, i.e. the airway characters and the airport types and reveals the domination of the hub-regional routes in the net- work. The annual transport of over 50,000- 100,000 passengers signifies the maturity of a regional route. The air routes of some regions, e.g. northwest, mid-north, southwest, and mid-east, mainly serve the regional demands, while those of northeast and mid-south are driven by the connecting demands with adja- cent regions. To develop the RAN, an airport of over 10 regional air routes should improve the route transport accessibility, and better meet the demands within the region where the airport is located.
