In this work, the exact dynamics of excitation in the generalizedAubry-Andr\'{e}-Harper model coupled with an Ohmic-type environment isdiscussed by evaluating the survival probability and inverse participationratio of the state of system. In contrast to the common belief thatlocalization will preserve the information of the initial state in the systemagainst dissipation into the environment, our study found that stronglocalization can enhance the dissipation of quantum information instead. By athorough examination of the dynamics, we show that the coherent transitionbetween the energy state of system is crucial for understanding this unusualbehavior. Under this circumstance, the coupling induced energy exchange betweenthe system and its environment can induce the periodic population of excitationon the states of system. As a result, the stable or localization-enhanceddecaying of excitation can be observed, dependent on the energy differencebetween the states of system. This point is verified in further by checking thevarying of dynamics of excitation in the system when the coupling between thesystem and environment is more strong.
