  In this paper, we explore the localization transition and the scaling
properties of both quasi-one-dimensional and two-dimensional quasiperiodic
systems, which are constituted from coupling several Aubry-Andr\'{e} (AA)
chains along the transverse direction, in the presence of next-nearest-neighbor
(NNN) hopping. The localization length, two-terminal conductance, and
participation ratio are calculated within the tight-binding Hamiltonian. Our
results reveal that a metal-insulator transition could be driven in these
systems not only by changing the NNN hopping integral but also by the
dimensionality effects. These results are general and hold by coupling distinct
AA chains with various model parameters. Furthermore, we show from finite-size
scaling that the transport properties of the two-dimensional quasiperiodic
system can be described by a single parameter and the scaling function can
reach the value 1, contrary to the scaling theory of localization of disordered
systems. The underlying physical mechanism is discussed.
