The invention discloses a routing resource control method suitable for a double-layer satellite optical network data relay system. The routing resource control method comprises the following steps: 1, establishing a time-sharing hierarchical clustering network management model; 2, adopting time-sharing management of periodic discretization, wherein time slices are divided; in order to simplify difficulties brought to route selection and maintenance by time-varying characteristics of a relay satellite system topology and a load in a double-layer satellite optical network, equally dividing a system period into n time slices; 3, enabling each satellite in the double-layer satellite system to upload the existing planned task condition; 4, reporting a data relay forwarding demand of each user star; 5, enabling the GEO management satellite to adopt an LBDRA algorithm to calculate the route of a new task according to the requirement and the existing task condition of each satellite; 6, enabling the GEO management sa
