The S-ordering expansion of density operator of coherent state is obtained by means of the generalized Weyl quantization scheme. Based on this S-ordered expression and the technique of integration within S-or-dered product of operators，we derive the S - ordering forms of some quantum operators (including normally ordered，Weyl ordered and antinormally ordered product of operators). The proposed method further expands the application of the coherent state on the ordering of quantum operators.
