This paper briefly describes the initiative of the earth system dynamic model, recent international and domestic progress on the model development and its numerical simulations. As the mathematical representation of the integrated evolution of coupled climate, ecosystem and environmental system, earth system dynamical model can be applied for the longterm simulation in order for the understanding and prediction of climate and environmental change from global to regional scale, hence for the disaster prevention and mitigation, and the planning for sustainable development. At present, there is no practical earth system model available for the real applications, and it will take about two to three years′ efforts in order to have such an integrated model system.
