内地机场航空物流辐射范围及格局演变研究

Delimitation and Evolution Pattern of Chinese Airports′Aviation Logistics Space Radiation Scopes

为了合理测定机场航空物流辐射范围并研究区域内机场格局演变规律,运用主成分分析法对内地19个机场2007、2012、2017年的航空物流综合实力进行评价,接着采用基于断裂点模型的加权Voronoi图法对各机场3 a的航空物流辐射范围进行划分,揭示其动态演变规律,分析格局演变影响因素。研究发现:我国内地机场在航空物流综合实力上呈现出“东南高,西北低”的地域特征;2007—2017年间辐射范围呈扩张状态的机场大多位于我国中西部地区,东南沿海、华北、东北地区机场的物流辐射范围大多无明显变化或呈收缩状态;机场所在城市整体经济与外向型产业发展水平逐渐成为影响机场航空物流发展的关键因素。

It was significant to delimit reasonably the space radiation scope of airport aviation logistics and to study on the evolution pattern of airports in the development and decision-making of airport.The principal component analysis method was used to evaluate the aviation logistics comprehensive strength of 19 large airports in 2007,2012 and 2017 in China.On the basis of this,the weighted Voronoi diagram method based on the breaking point model was adopted to divide the aviation logistics radiation scope of each airport,which revealed their evolution pattern and influencing factors of evolution in recent years.The paper drawed the following conclusions:China′s eastern and southern airports had strong comprehensive strength in aviation logistics,that of western and northern regions was weak.In recent years,most of the airports that their aviation logistics radiation ranges expanded,were located in the central and western regions of China.Most of the airports that their radiation ranges shrank and had no significant change were located in the southeast coast,north and northeast of China.The overall economic and export-oriented industry development of the city where the airport was located had gradually became key factors affecting the development of airport aviation logistics.
