A method for dynamically allocating resources is disclosed. The method is used in a base station and includes: dividing a coverage zone into a plurality of geographic zones, wherein each geographic zone corresponds to a resource pool; finding a first geographic zone based on geographic location information, wherein a resource utilization rate of resource blocks in a first resource pool corresponding to the first geographic zone is highest; determining whether resource pools corresponding to a plurality of adjacent geographic zones of the first geographic zone are reused; and allocating the resource blocks in the resource pools corresponding to the adjacent geographic zones to the first resource pool.
