Abstract
In this paper, we develop a simple method for the reconstruction of the string-inspired dark energy model with the lagrangian $ {\cal L} = -V (Ï) \sqrt{1 - α' {\nabla}_μ Ï\nabla^μ Ï+ β' Ï\Box Ï} $ given by Cai et. al., which may allow the equation-of-state parameter cross the cosmological constant boundary . We reconstruct this model in the light of three forms of parametrization for dynamical dark energy.
