The embodiment of the invention provides a gas turbine inlet air temperature control system which comprises a gas-steam combined cycle unit and a heat exchange mechanism, the heat exchange mechanism comprises an air heat exchanger, and an air outlet of the air heat exchanger communicates with an air inlet of an air compressor of a gas turbine; the water inlet end of the air heat exchanger is connected with a heat exchange water inlet pipeline, and a third valve is arranged on the heat exchange water inlet pipeline and used for controlling water circulation in the heat exchange water inlet pipeline. The water outlet end of the air heat exchanger is connected with a heat exchange water outlet pipeline, and a fourth valve is arranged on the heat exchange water outlet pipeline and used for controlling water circulation in the heat exchange water outlet pipeline. A cooling water inlet pipe is led out of the heat exchange water inlet pipeline to convey cooling media, and a first heating water inlet pipe and a second heating water inlet pipe are led out to convey heating media. Switching of cold and hot media of the air heat exchanger is controlled through the multiple valves, the purpose of increasing or reducing the gas inlet temperature of the gas turbine according to the actual operation condition is achieved, and different requirements of a unit are met.
