In this paper, a finite difference scheme of two-dimensional parabolic equation is constru-cted in a non-rectangular mesh by the integral method. For an arbitrary quadralateral mesh, anine--point scheme is obtained by using certain interpolation formulae. Meanwhile, an economicalscheme is established and some numerical results are given.
