In this paper, we study locally projectively flat Finsler metrics with constant flag curvature K. We prove those are totally determined by their behaviors at the origin by solving some nonlinear PDEs. The classifications when K= 0, K=− 1 and K= 1 are given respectively in an algebraic way. Further, we construct a new projectively flat Finsler metric with flag curvature K= 1 determined by a Minkowski norm with double square roots at the origin. As an application of our main theorems, we give the classification of locally projectively flat spherical symmetric Finsler metrics much easier than before.
