The invention discloses an aircraft test snow raising environment simulation system and simulation method, and relates to the technical field of aircraft tests. The simulation system comprises an air inlet barrel and a plurality of snow rakes which are located at the tail end of the air inlet barrel and arranged in a matrix mode, and the air inlet barrel is sequentially provided with an air inlet section, an axial flow fan, a round-square transition section, a rectification section, a static flow section and a snow raising section from front to back; a heat preservation cavity and a water storage cavity are formed in the front end in the snow rake side by side, the rear end of the water storage cavity is connected with an electromagnetic valve through a branch pipe, the rear end of the electromagnetic valve is connected with an auxiliary crystallization assembly through a water conveying pipe, and the periphery of the middle of the water conveying pipe is sleeved with a heat supply cavity. The auxiliary cryst
