The invention relates to a dynamic spectrum distribution method based on covering frequency in a heterogeneous wireless network. The method is characterized by comprising total frequency spectrum benefit maximization and interference control, wherein the interference control is based on a coverage probability threshold, and the interference control model is p[n,m](A)>=beta n (1); and based on the interference control model, modeling of a covering frequency based dynamic spectrum distribution algorithm (CP-DSA) is defined in the description in the interference control model based on coverage probability, user signal interference noise ratio and base station coverage performance requirement are considered at the same time, starting from the purpose of ensuring the base station coverage probability requirement, to achieve the purpose of ensuring user service quality requirement in a cell; and by adopting the dynamic spectrum allocation algorithm CP-DSA based on covering frequency, the total frequency spectrum benefit can be improved, interference between base stations is effectively controlled, and under the condition of an actual shadow fading channel, the user SIR (signal interference noise ratio) requirement is met.
