摘要
固定的空中交通运行系统和功能已难以适应航路结构和空域需求的巨大变化,这引发了空域资源配置由静态为主向灵活动态的演进,时空连续数据的挖掘和应用支持了这个过程。综述近些年国内外相关研究成果可见:从基础要素的多维度表达到具体空域单元的特征分析均向实时方向深化与拓展并表现出新机制;引进时间参数开发了系列高密度航空流识别方法并与飞行路径跨时空模型相结合形成鲜明的动态特色;相关应用与实践均体现出空域资源配置的结构性革命,推动了空域拥堵、航班延误与资源分配等现实问题的解决。国外动态空域资源配置研究与实践对我国具有积极的借鉴意义。然而,在同时应对空侧能力发挥和多维度参数变化时,仍然面临时段-航段匹配、微观-宏观结合、终端空域-飞行航路对接、空域-地域一体化等方面的挑战。未来,地理学需进一步发挥自身优势,构建新的空域研究对象并深度开展研究工作。
Given that the fixed air traffic operation system and functions are difficult to adapt to the great changes of air route structure and airspace demand,the airspace resource allocation is undergoing an evolution from static to flexible and dynamic so as to effectively solve the contradiction between airspace capacity and actual demand. In this process,the dependence on spatiotemporal continuous data is gradually strengthened. This article reviewed the relevant national and international research,and found that from the multi-dimensional expression of basic elements to the feature analysis of specific airspace units,airspace resource allocation deepens and expands in a real-time direction and presents a new mechanism. A series of high density air traffic flow identification methods are developed by introducing time parameters and combined with the flight path model to form a distinct dynamic characteristic. Related applications and practice reflect the structural revolution of airspace resource allocation and promote the solution of practical problems such as airspace congestion and resource allocation. The research and practice of dynamic airspace resource allocation outside China have positive reference significance to our country. However,when simultaneously coping with the hoisting of airside capability and the change of multi-dimensional parameters,we still face the challenges of period-segment matching,micro-macro combination,terminal airspace-air route docking and airspace-land area integration. In the future,geography should further integrate the unique advantages of spatiotemporal interaction and construct a brand-new overall mobile chain of various airspace-land scales to carry out research work deeply.
