    The volume element methods for a kind of parabolic equations with variable coefficients on quadrilateral networks are proposed. The L2 norms best convergence order error estimates for both a semidiscrete and two full-discrete finite volume element schemes for parabolic equations with variable coefficients are presented on h2 quasi-parallel quadrilateral elements.
