Under the condition of airport autonomous operation, perception of the operational environment is a crucial factor constraining the realization of autonomous airport operations. In the process of airport surface traffic operation, understanding the utilization of surface movement resources is a key step in establishing a comprehensive operational environment. The surface movement process at airports is first focused on in this study, and an ontology model for airport surface movement processes is constructed. Based on the structural layout of the airport surface road network, the movement paths were divided, and a "node-edge" model based on the connection between network nodes was established. Meanwhile, building upon the ontology model, dynamic and static attributes of the surface road network were defined as the basic properties of network nodes. With network nodes as the research object, various conflict scenarios existing in aircraft surface movement processes were modeled based on the dynamic attributes of network nodes, thus achieving a dynamic representation of aircraft movement processes at network nodes. Using speed data generated by aircraft dynamics models as a basis, a visualization representation of dynamic graphs of surface movement resource utilization in the presence of aircraft conflict scenarios was designed. Experimental results demonstrate that the model effectively represents both conflict and conflict-free scenarios in surface operations. This enhances the overall perception of surface movement resource utilization among participants in airport surface traffic.
