The nonclassical properties of odd and even coherent states in a finite dimensional Hilbert spaces (FDHS) case are studied by numerical method． It is found that，no squeezing but antibunching efects exist in odd coherent states,both quadrature squeezing and antibunching efects are exist in even coherent states．with the number ofdimension reducing．the quadrature fluctuation is increased and the antibunching efects are Enhanced in odd coherent states； and the squeezing effects are weakened but the antlbunchlng efects aTe Enhanced iu even coherent stares
