Summary:The invention discloses a dynamic depriving type service transmission method of a space information network, comprising the following steps of: classifying transmitted services into a delay high-sensitive service and a delay low-sensitive service according to the delay sensitive degree of transmission service; regularly updating the occupied bandwidths and the demanded bandwidths of the transmission services in the network by a center control node in the network; when the occupied bandwidths of the transmission services are larger than the demanded bandwidths, recovering surplus bandwidth resources to an idle bandwidth pond; when the occupied bandwidths of the transmission services can not meet the bandwidth demand of the delay high-sensitive service, distributing bandwidths for the transmission services from the idle bandwidth pond; and when the idle bandwidth pond can not meet the bandwidth demand of the delay high-sensitive service, and preferentially transmitting the delay high-sensitive service by depriv
