The Lee weight enumerator for linear codes of length n over the ring R= F2 + uF2 + vF2 + uvF2 are defined and the Lee weight MacWilliams identity for linear codes of length n over the ring R are given. Furthermore, by means of Krawtchouk polynomials, the equivalent Lee weight MacWilliams identity for linear codes of length n over the ring R are obtained.
