It is proved that Lukasiewicz implication is an ideal implication, and Reichenbach implication is not an ideal implication.

On the basis of the synthetical analysis of ten important implication operators and sixteen restrictive conditions of implication operators, the author puts forward a kind of important implication operators-ideal implications and discusses their restrictive conditions.

Based on the 19 properties which is used to verify the fuzzy implications,some well-known fuzzy implications which include reasoning implication,basic implication and value-maintained implication are introduced.

This paper has introduced the notion of fuzzy implicative ideals in BCK-algebras ,and given some equigalent conditions in which a fuzzy ideals would be a fuzzy implicative ideals,and further characterized the homomorphic properties of fuzzy implicative ideals.
