Motivated by national low -altitude economic strategies and advances in next -generation aviation technologies，low -altitude logistics，as an integral part of intelligent transportation，is greatly boosting the development of a novel logistics network characterized by integrated aerial and terrestrial systems.This study aims to develop an efficient，secure，and intelligent low -altitude logistics system，with a focus on addressing logistics bottlenecks in mountainous regions and complex urban and rural settings，thus enhancing spatial coverage and last -mile delivery efficiency and fostering the green and intelligent transformation of the logistics sector.The performance characteristics and applications of four types of unmanned aerial vehicles （UAVs），namely multi -rotor UAVs，fixed -wing UAVs，electric vertical takeoff and landing （eVTOLs），and winged -parachute UAVs，were systematically analyzed，highlighting their distinct and complementary advantages in terms of range，payload，environmental adaptability，and operational cost.With an emphasis on low -altitude airspace classification standards and operational management frameworks，and structured urban airspace modeling and intelligent route planning technologies were utilized，and applicable route planning strategies across varied terrain conditions were analyzed.As a result，an optimized framework for low -altitude logistics networks was proposed，and a comprehensive operational system encompassing takeoff and landing sites，energy supply facilities，flight supervision，and logistics scheduling was established to enhance system -level integration and synergy.There are several bottlenecks in the development of low -altitude logistics，including outdated airspace policies，inconsistent airworthiness certification standards，high operational costs，and inadequate flight safety assurances.To facilitate the deep integration of low -altitude logistics with intelligent transportation，coordinated efforts are required across four policies，standards，operations，and technologies：accelerating airspace reform，enhancing UAV airworthiness certification systems，exploring sustainable operational models，and developing an eco-friendly low -altitude logistics system supported by intelligent scheduling and precise supervision.
