灵活空域使用以及实践已成为美国新一代航空运输体系的关键组成部分,同时也成为欧洲和日本等国家空域重构的重要技术支撑。在全面认知与回顾灵活空域使用的产生、实施与目标的基础上,对扇区边界更改的设计方法进行了优势评估;然后从"扇区拆合"视角分析了扇区边界更改的效果;由此解释了灵活空域使用的时间替代机制。研究认为,"算法+人工动态扇区边界更改"能更好地分配和平衡跨扇区的非均衡变化,促进空域资源开发和空域容量释放;建立在信息通信技术支持下的灵活空域使用实现了时间因素对空间利用的替代,能最大限度地提高空域重构和航线改变的灵活性。灵活空域使用方法及其应用不仅可以服务于我国国家空域系统整体战略的制定,也有助于推动地理学关于空域资源开发利用研究及其空陆对接研究。
The flexible use of airspace and its practice are the key components of next generation air transportation system and the important technical support of reconstructing the national airspace in Europe,Japan and other countries. On the basis of overview and comprehensive cognition of the generation,implementation and aims of flexible use of airspace,the design methods of sector’s boundary changes were evaluated. Then,from the perspective of"sector-closed",the effect on sector boundary changes was evaluated,and the time alternative mechanism in flexible use of airspace was revealed. The research shows that "Algorithm + Manual Dynamic Boundary Change"can be a method for better distribution and balancing the unbalanced traffic demand across regions,which will also promote the airspace development and capacity release. The flexible use of airspace based on ICTs realizes the replacement of the factor of space by the factor of time,which enhances the flexibility of airspace configuration and the changing of air routes to the maximun extent. The methods and applications of flexible use of airspace will be not only beneficial to establishing the whole national airspace system and utilization,but also to promoting geography research on airspace resources development and the studies on connection between air and land.
