摘要
In order to describe quantitatively the cation exchange action between water and rockand the transport behavior of exchange cations in the process of sea water intrusion, a newthree-dimensional mathematical model, which can simulte simultaneously the transport be-havior of exchange cations Na<sup>+</sup>, Mg<sup>2+</sup> and Ca<sup>2+</sup> is set up. This model is applied in prac-tice and the simulated values agree very well with the field data.
