The invention relates to a beam forming optimization method and system of a holographic antenna based on discrete amplitude regulation and control. According to the beam forming optimization method of the holographic antenna based on discrete amplitude regulation and control, a digital beam forming scheme is obtained based on radiation amplitude and channel matrix design on the basis of a communication process between a base station comprising a reconfigurable holographic metasurface and a user; and after a holographic beam forming scheme is designed based on the transmission characteristics of the electromagnetic waves on the reconfigurable holographic metasurface, a final holographic beam forming scheme is determined in an iteration mode by adopting a joint optimization algorithm, and finally, a transmitted signal is processed according to the final holographic beam forming scheme, the total data rate of users is maximized while the blank that the influence of a holographic beam forming scheme based on disc
