Considering the current dilemma the environmental design methodology is facing, the paper analyzes the characteristics of environmental design ecology methodology based on the theory of affordance. It is shown that the methodology takes ecological holism as the cornerstone of environmental design method research and takes ecological law as the basic criterion of environmental design. The affordance connotation, the mechanism of human-environment coordination, is taken as the principle and method of environmental design so as to achieve the coordination between human and environment at the level of behavior and the resonance at the level of emotion, to achieve transcend the function of human design， and construct the ecological self from the aspects of ecological practice and ecological experience.
