The invention provides a low-energy-consumption vertical take-off and landing unmanned aerial vehicle with laminar flow optimization design and a control method. The unmanned aerial vehicle comprises a fuselage, wings, an avionics system and a duct power system. Wherein the wings are fixedly mounted at the middle lower parts of two sides of the fuselage; the avionics system is fixedly arranged at the front section of the fuselage; the duct power system is mounted at the tail of the fuselage; laminar flow optimization design is adopted for the wings, wing surface adjusting mechanisms are arranged in the wings, and the wing surface adjusting mechanisms conduct dynamic adjustment on wing profiles on the aerodynamic characteristics of the wings based on the duct power systems 4 under various flight working conditions. The laminar flow technology is adopted for the unmanned aerial vehicle and the wings, optimization design is carried out by considering the influence of a duct power system, the resistance of the wh
