英文摘要：
In this paper, a finite volume element （FVE） formulation for two-dimension solute transport problems is derived, error estimates between FVE solutions and accurate solutions are provided. It is shown by numerical examples that FVE formulation is stabler that finite element formulation for solving two-dimension solute transport problems,
