Abstract

The present paper is the review of of holographic dark energy (HDE) model
and varies Modified Gravity theories .It is a theoretical attempt of applying the
holographic principle (HP) to the dark energy (DE) problem. We make use of HP and the
dimensional analysis, we derive the general formula of the energy density of HDE. Then, we
describe the properties of HDE model, in which the future event horizon is chosen as the
characteristic length scale. Furthermore, we discuss HDE scenario in various modified
gravity (MG) theories, such as Brans-Dicke theory, Braneworld theory, scalar-tensor theory,
Horava- Lifshitz theory, and so on. Besides, we introduce the attempts of reconstructing
various scalar-field DE and MG models from HDE. Finally, we make comparisons among
various gravity theories and studied about future reseach in this era.
