This paper discusses a randomized Logistic equation N（t）=（r+αB（t））N（t）[1-（N（t）/K）] with an initial value N（0）=N0,and N0 is a random variable satisfying 0＜N0＜K.The existence, uniqueness and global attractivity of positive solutions and maximum likelihood estimate（MLE）of the parameters of the equation are studied.
