We investigate the mechanism of spin gap formation in a two-dimensional model
relevant to Mott insulators such as CaV$_4$O$_9$. From the perturbation
expansion and quantum Monte Carlo calculations, the origin of the spin gap is
ascribed to the four-site plaquette singlet in contrast to the dimer gap
established in the generalized dimerized Heisenberg model.
