Abstract: With the advancement in technology and coming of information era,the development of architecture surface is in an unprecedented flourishing situation,characteristics of the skin becomes a direct reflection of architectural features.A softening trend occurs in eco-building skins.The occurrence of this trend is based on science and undergone a rational thought.By borrowing botanical science and hidden building body mass,fuzzy boundaries of architecture and environment;by borrowing physical science to create a complex surface skin,it is softened the interface between the architecture and environment;by borrowing bionics theory,it is simulated biological skin texture,thus reducing the differences in manual architectures and environment.Using perfect ecologic architectural form to promote ecology has gradually become a new creation mode.
