We have studied the quantum corrections to the resistance of two-dimensional (2D) percolation networks of quasi-one-dimensional (1D) wires in which the ratio between the percolation correlation length ξ and the quantum lengths , LT could be controllably changed over a wide range. We have shown that the percolation networks behave like homogeneous 2D conductors with respect to the quantum corrections if ξ<LT. Close to the percolation threshold (ξLT) a crossover to 1D quantum corrections is observed.
