中国主要城市低空适飞空域分析
Analysis of low altitude flyable airspace in major cities in China
摘要
Abstract
[Background]The refined management of airspace resources has a significant impact on the development of the low-altitude economy.The assessment of low-altitude airspace airworthiness is a key prerequisite for low-altitude airspace management,but the mechanism by which it is influ-enced by the built environment on the ground has not yet been systematically analysed.[Objective]Assess the airworthiness and spatial developability of low-altitude airspace in cities,and reveal the mechanisms by which the built environment on the ground affects it.[Methods]Based on multi-source geospatial data,a low-altitude airworthiness identification framework was constructed that in-cludes the delineation of no-fly buffer zones,spatial aggregation analysis(global/local Moran's in-dex),and regression analysis of influencing factors(OLS).[Data]Fifty-five cities in China were se-lected,and multi-source data such as GHS-UCDB-2024,OpenStreetMap/Amap POI,and 3D-GloB-FP building heights were integrated for analysis using a 1 km hexagonal grid as the unit.[Results]The proportion of airspace suitable for flight in cities ranges from 54.17%to 99.82%,showing spa-tial differentiation with"core cities being restricted and non-core cities being relaxed"and a signifi-cant positive correlation.The natural obstacle ratio,urban compactness,and urban area are positively correlated with the proportion of airspace suitable for flight,while the proportion of low-altitude risk facility areas is negatively correlated.The spatial agglomeration layout of functional zones has a stronger constraining effect on flight suitability than their size.关键词
