The invention provides a pipeline cathodic protection output adjustment system and an adjustment method. The pipeline cathodic protection output adjustment system is characterized by comprising a plurality of corrosion rate probes, a control terminal, an anode ground bed, a potentiostat and a plurality of intelligent potential acquisition devices, wherein the plurality of corrosion rate probes andthe plurality of intelligent potential acquisition devices are correspondingly adjacent and arranged in the soil on one side of the pipeline along the extension direction of the pipeline, and are allelectrically connected to the control terminal, and the intelligent potential acquisition devices are also connected to the adjacent pipelines through wires; the anode ground bed is buried in the soil on one side of the pipeline and is connected to the potentiostat through a wire; and the potentiostat is electrically connected to the control terminal and connected to the pipeline through a wire.Accordingly, the pipeline c
