The gas-electricity graded heating system comprises a gas heat exchange device and an electric heating system, a main exhaust gas input pipeline and a main exhaust gas output pipeline of a main engine serve as stair handrails, a heat dissipation pipeline is laid on the lower surfaces of steps, and the two ends of the heat dissipation pipeline are connected with the main exhaust gas input pipeline and the main exhaust gas output pipeline correspondingly. Melting ice by using heat energy of host waste gas; and the electric heating system is used for precisely controlling the heating system to melt ice in a graded manner according to detection results of the first temperature sensor, the second temperature sensor, the humidity sensor and the current detection device. The gas heat exchange device and the electric heating system are matched with each other, heat energy of waste gas of the main machine is fully utilized to be matched with the electric heating system, uniform heating is achieved, the heating level is adjusted and controlled timely and accurately, and electric power resources are saved while the ice melting efficiency is improved; meanwhile, the problem that the heat exchange device is not deiced in time in severe weather is solved; the system is simple in structure and low in cost, and effectively prevents people from being injured due to slipping caused by freezing.
