  We introduce the 5-dimension dynamical holographic QCD model, which is
constructed in the graviton-dilaton-scalar framework with the dilaton
background field $\Phi$ and the scalar field $X$ responsible for the
gluodynamics and chiral dynamics, respectively. We review our results on the
hadron spectra including the glueball and light meson spectra, QCD phase
transitions and transport properties in the framework of the dynamical
holographic QCD model.
