Based on the high precision experimental data released by the CLASCollaboration recently, the interaction mechanism of the photoproduction of$\Lambda$(1520) off a proton target is investigated within aRegge-plus-resonance approach. With the decay amplitudes predicted in theconstituent quark model, the roles played by nucleon resonances are studied. Itis found that $N(2120)$ provides the most important contribution among thenucleon resonances predicted in the constituent quark model. The $t$ channelcontribution with Regge trajectories and the $\Lambda$ intermediate $u$ channelare responsible to the behaviors of the differential cross section at forwardand backward angles, respectively.
