Abstract: In this paper, we aim to discuss the evolvement of the dark energy that is assumed to be in the Scalar-tensor gravity. We derive and analyze the characteristics of this kind of dark energy model which exceed the general relativity framework, and compare the difference between the Sca-lar-tensor dark energy models and the general dark energy models. At last, with the current observational constraints, we choose a special model from the Scalar-tensor models to get the nu-merical calculation, and obtain results which is difficult for the general single scalar field model in the general relativity framework.
