Provided in the present disclosure is a treatment planning method comprising, acquiring a preset dose distribution scheme； generating a plurality of radiation dose distribution schemes according to a preset algorithm and equipment parameters of a radiotherapy system, wherein the equipment parameters of a radiotherapy system comprises one or more of the radiation energy, parameters of radiation field, radiation angle, dose distribution at different radiation angles, and radiation time； comparing the plurality of radiation dose distribution schemes to the preset dose distribution scheme, to determine at least one radiation dose distribution scheme that is closest to the preset dose distribution scheme； and making a treatment plan according to the determined radiation dose distribution scheme.
