对于高斯增强型混沌光场，采用有序算符内的积分理论，我们导出了其P-表示。给出P-表示与Wigner 函数关系的新推导，从而由高斯增强型混沌光场的P-表示给出其Wigner函数。

For the Gaussian enhanced chaotic light field, by virtue of the technique of integration within an ordered product of operators (IWOP), we derive its P-representation. Further, the relationship between the P-representation and the Wigner function is derived in a new way, hence from the P-representation of the Gaussian enhanced chaotic light field the corresponding Wigner function is obtained.
