We study the effects of nuclear shadowing and the subsequent enhancement for the spin structure function g1A(x, Q2) in polarized DIS on 7Li and 3He. These effects are found to be quite significant - the magnitude of nuclear shadowing at x ≈ 10-3 is of order 16% for gn.s. 3/21A=7(x, Q2)/gn.s.1N(x, Q2) and 10% for gn.s1A=3(x, Q2);/gn.s.1N(x, Q2); the enhancement at x ≈ 0.125 (0.15) is of order 20 (55)% for gn.s. 3/21A=7(x, Q2)/gn.s.1N(x, Q2) and 14 (40)% for gn.s.1A=3(x, Q2)/gn.s.1N(x, Q2).
