Abstract：
The generalized q-coherent state of the quantum group SU_q(2) is defined.The q-coherent state realization of the quantum algebra SU_q(2) is given.This realization may be considered as q-Dyson realization.In analogy to the usual Lie algebra SU_q(2),the q-Holstein-Primakoff representation is also found from the q-Dyson representation.The transformation matrix between the q-Dyson and Holstein-Primakoff representation is obtained.
