The invention discloses a surface distributed ventilation resistance reduction system and method for overcoming underwater back pressure difference interference, and belongs to the technical field of underwater resistance reduction. Comprising a gas supply system, a gas conveying system and a gas release system which are communicated in sequence, the gas supply system provides a high-pressure gas source, pressure, flow speed, temperature and flow control is carried out on high-pressure gas, the treated high-pressure gas is shunted and then introduced into the gas release system through the gas conveying system, and the high-pressure gas is released on the drag reduction surface to form a uniform gas film layer; the gas conveying system is composed of a branch pipeline and a plurality of capillary tube bundles arranged in parallel and generates pressure drop on the gas supply system. The gas release system is composed of a plurality of gas release units which are arranged in one-to-one correspondence with the capillary tube bundles, and high-pressure gas introduced into the capillary tube bundles is buffered and then evenly released to the drag reduction surface. The influence caused by backpressure difference interference of an existing gas transportation pipeline is overcome, and the uniformity of a gas film layer on the surface to be subjected to resistance reduction can be improved.
