The invention discloses a multi-beam power distribution based overocean communication QoS guaranteeing method. The method specifically comprises the following steps of 1, building a capacity model ofa single beam of a multi-beam spherical digital phase control array based on a spherical digital phase control array beam power synthesis principle and different communication links which different beams of the overocean communication system locate; 2, building a multi-beam spherical digital phase control array power optimization problem model; and 3, performing approximate solution on the optimization problem by adopting Lagrange's auxiliary function and dichotomization. The power distribution scheme of the invention not only can copy with a fluctuation condition of a flow demand, but can also utilize the power resource efficiently, can obtain good system performances, and can guarantee the communication QoS level of different communication links of the spherical phase control array. 种基于多波束功率分配的海洋通信QoS保障方法，该方法具体包
