Civil unmanned aerial vehicles（UAVs）have a vast market. However, due to the lack of supervision, incidents which threaten public safety frequently take place. We takle the problem of UAV supervision, and study the life cycle of UAV and present the idea of full-life-cycle supervision on UAV. Then, we discuss full-life-cycle supervision on UAV through three aspects, including function division of supervision institution, regulations establishing and perfecting, as well as laws enacting and updating continuously. Meanwhile，we offer a way of establishing supervision system on UAV through task clarifying, responsibility defining, goal setting, flow regulating, measures making and law forming. We emphasize on regulations establishing and perfecting, and put forward the suggestion of streamline administration and institute decentralization on UAV supervision.
