For the anisotropic parabolic equations, we introduce a multilevel wavelet-like block incremental unknowns(WBIU) method and then, based on this new method, we construct a WBIU-type Crank-Nicholson scheme. The stability of this scheme is carefully studied. The numerical results show that the condition number of the coefficient matrix of the linear system correspond to this scheme is reduced efficiently for ε small, and these results also validate the stability of this new scheme.
