Holographic dark energy models have got tremendous enthusiasm recently both from theoretical and observational point of view.In the present work we assume that the universe is dominated by dark matter (DM) and dark energy (DE) which do not evolve separately but interact nongravitationally with one another.We consider different holographic dark energy (HDE) models characterized by the IR cut off lengths.We show that the interacting HDE model can be considered as the unified DM and DE model.Finally,we establish the equivalence between HDE with different scalar field models.
