Abstract: In formal context，it is inevitable to the existence of attribute dependency.So it is meaningful that attribute dependence formulas are applied to the concept lattice’s construction.After given some definitions about attribute dependence formula’s expression and reduction，the method is presented，that is，formal context and attribute dependence formulas reduced are as input data，while considering attribute implication between attributes.Finally need not construct an entire concept lattice，only construct a concept lattice based on the attribute dependence formulas.Aim at speeding up to construct concept lattice based on some attribute dependency formulas，showing the concept hierarchy and discovering much potential concept information.

Key words: concept lattice, attribute dependency formulas, attribute implication
