The invention relates to the technical field of gas boiler control, in particular to a heat supply gas unit heat load online switching control method and system. Comprising the steps that operation parameters of a gas unit and a gas boiler are obtained, and a calculation function, constraint conditions and a regulation and control strategy are preset; initial output and initial operation states of the gas unit and the gas boiler are obtained, the output power of the gas unit, the output power of the gas boiler and the predicted load power are calculated in real time, and the gas consumption rate of the gas unit is calculated according to the gas consumption-output function of the gas unit in combination with the power generation gas consumption coefficient of the gas unit; and according to the gas consumption rate of the gas unit, the calculation function and the constraint condition, a regulation and control strategy is determined through a particle swarm algorithm. The heat supply stability of the unit is e
