The invention relates to the technical field of wireless communication, in particular to a wireless resource allocation optimization method and device oriented to a semantic communication scene. The semantic communication scene-oriented wireless resource allocation optimization method comprises the following steps of: acquiring a text sequence to obtain semantic information; performing wireless resource allocation according to the local initial parameters and the semantic information to obtain an allocation bandwidth; transmitting and recovering the semantic information based on the allocated bandwidth to obtain a recovered text; according to the distribution bandwidth and the semantic spectrum efficiency, optimization is carried out through a distributed near-end strategy optimization algorithm, and local update parameters and a local loss function are obtained; aggregation is carried out through a federated average algorithm, and global aggregation parameters and a global loss function are obtained; when th
