Abstract： Traditionally, the real estate ownership is divided into that of the surface, the upper part of the surface and the lower part of the surface of the earth. The development and legislation of underground space are developing rapidly, and the development and utilization of air space are relatively slow. In recent years, the new technological products represented by unmanned aerial vehicle (uav) have triggered off mans demand for the right of the upper space of the earth surface. However, the nature and exercise of air space rights still need to be explained and clarified by law. There is the objective existence of a separate ownership for the space above the surface of the earth, that is, air space right. It is a property right owned by the state or a collective. At present, the exercise of this right is dominated by public power. However, its exercise should not exclude the legitimate appeal of private rights. The goal of exercising rights is to balance the freedom and limitation of rights. It is necessary to define the ownership attribute of air space right from plane land law to threedimensional space law.
