Group 1 - The core concept of low-altitude cargo transportation involves using drones and eVTOLs to perform delivery tasks below 1000 meters, enabling direct connections from storage centers to delivery endpoints, thus extending delivery services from the "last mile" to the "last meter" [1] - Currently, low-altitude cargo transportation in China is in a small-scale exploratory phase, primarily focused on remote areas and regions where traditional logistics are difficult to cover, addressing challenges of high costs and coverage limitations [1] - The development phase features parallel advancements in technology validation and policy trials, with local governments actively establishing foundational airspace management and safety standards, although commercial maturity remains low [1] Group 2 - As technology matures and the policy environment improves, low-altitude logistics is expected to expand significantly into urban peripheries and sub-central areas, transitioning to a normalized operational model [2] - Anhui Province, as a pilot for low-altitude airspace management reform, has established a complete industrial chain from research and manufacturing to operational services, with hundreds of low-altitude enterprises gathered [2] - The launch of drone logistics delivery routes in Hefei in 2024 marks a shift from experimental to practical phases, showcasing the potential of low-altitude logistics through successful operations in areas like Huangshan and Anqing [2] Group 3 - Despite rapid development, low-altitude logistics faces challenges such as insufficient endurance, weak communication security, and safety risks under adverse weather conditions, necessitating systematic solutions [3] - The increasing number of low-altitude flying vehicles presents new challenges for airspace management, requiring efficient utilization while ensuring safety [3] - Promoting healthy development in low-altitude logistics requires coordinated efforts from government, enterprises, and society, including establishing a comprehensive regulatory framework and improving infrastructure [3]
