A method for controlling a clothing drying apparatus, the clothing drying apparatus comprising a drying drum and a heating device, wherein a drying process of the clothing drying apparatus comprises a load determining stage, a first heating stage, a second heating stage, an extra drying stage and a cold air stage that are run in sequence, and the control method comprises:
determining a size of load in the load determining stage;
when the load is a small load, judging whether the load comprises a high-water-content load in the process of running the first heating stage by the clothing drying apparatus; and
controlling the first heating stage to run for at least a first preset time if the load comprises a high-water-content load;
wherein the step of judging whether the load comprises a high-water-content load further comprises:
acquiring a plurality of humidity values of the load successively; and
if a difference between one humidity value and a previous humidity value thereof in the plurality of humidity values is larger than or equal to a first humidity threshold, then determining that the load comprises the high-water-content load.
