  Recently AMS-02 collaboration publish their measurements of light cosmic-ray
nuclei, including lithium, beryllium, boron, carbon and oxygen. All of them
reveal a prominent excess above $\sim$ 200 GV, coinciding with proton and
helium. Particularly, the secondary cosmic rays even harden than the primary
components above that break. One of the viable interpretations for above
anomalies is the spatial-dependent diffusion process. Such model has been
successfully applied to multiple observational phenomena, for example primary
cosmic ray nuclei, diffuse gamma ray and anisotropy. In this work, we
investigate the spatial-dependent propagation model in light of the new
observational data. We find that such model is able to explain the upturn of
secondary spectrum as well as the primary's. All the spectra can be well
reproduced and the calculated ratios are also in good agreement with the
observations.
