The invention discloses a gas turbine air inlet temperature control system based on a ground source heat pump and a control method of the gas turbine air inlet temperature control system. The system can utilize energy of an electrically-driven expansion type heat pump or an absorption type heat pump to conduct seasonal cooling or heating, circulating water subjected to heat exchange is pumped in winter (or from a ground source heat pump unit), the heat supply efficiency of the heat pump is improved through heat pump circulation, hot water is provided through the heat pump for heating to raise the gas inlet temperature of a gas turbine, so that load efficiency the part with the unit is improved; and circulating water which is not subjected to heat exchange yet before a condenser is extracted in summer (or from a ground source heat pump unit), the cooling efficiency of the heat pump is improved through heat pump circulation, then cold water is provided through the heat pump for cooling to lower the gas inlet te
