The invention discloses a novel metamaterial seismic isolation barrier with an adjustable frequency band gap, and belongs to the technical field of seismic protection, the novel metamaterial seismic isolation barrier comprises a plurality of novel resonators, the novel resonators are distributed in a rectangular array, and each novel resonator comprises a top cover plate, an outer shell, a bolt, a spring set and a core mass block. According to the novel resonator structure with the adjustable frequency band gap, the springs with the adjustable rigidity and the core mass block with the adjustable density are adopted, so that the resonance characteristics of the novel resonator structure with the adjustable frequency band gap can be fully exerted, band gaps with different frequencies can be generated, and when the novel resonator structure interacts with seismic waves in different frequency ranges, the seismic waves can be flexibly isolated; and surface waves harmful to existing buildings in seismic waves in di
