选取国内空港130个、航线317条,国际空港72个、航线237条,从空港和航线两个角度探讨我国航空货运机场分布格局和网络结构,结果发现:华东区、华北区、中南区是航空货物的主来源地、目的地和中转地,上海、广州和深圳、北京构成我国航空货运的"三极",形成货运三角;航空货运主要分布在少数枢纽空港间的航线上,呈现集中状态,前五位航线的货运量之和为43.83万t,占27.33%;航空货运高度集中在人口100万以上的城市间,人口100万以下的城市间航空货运联系很弱,所占市场份额之和不足1%,中等城市之间、大城市与中等城市、小城市之间无直航航线联系;我国对外航空货运联系主要集中在北美、日韩、西欧和港澳地区,与东欧、中东和南亚地区的航空货运联系较弱,与非洲和拉美地区目前还没有直通航班。
