Abstract: With the process acceleration of our agricultural and transformation，mass and technical production of agriculture has become mainstream of agricultural production.Therefore，it is imperative to specialization unified control and treatment.As an emerging technology，compared with the traditional plant protection machine，efficiency and effect of injection，prevention and control of plant protection unmanned aerial vehicles were improved significantly.It was especially suitable for large area crop production of plant protection spray.Based on the future development direction of China′s agriculture，plant protection unmanned aerial vehicle in the future would become the main agricultural specialization work force of unified control and treatment.Combined with the agricultural development and present situation of plant protection unmanned aerial vehicle in Beijing，promotion prospect of plant protection unmanned aerial vehicle was analyzed，and preliminary suggestions of development were put forward.
