Abstract: In this paper,chaology,fractal geometry and other related newly developed non-linear theories have been introduced into the study of traditional Chinese architectural and garden design,and "Feng- shui",the theoretical source of space analysis and design.We argue that traditional Chinese architectural space concept is a kind of chaological space concept,and its form generation mechanism is more related to fractal geometry,which pursues a non-linear order (involving both linear and non linear transformations).On this basis,we proposed a study on "chaotic/fractal architecture",a set of new theories and methods for architectural and urban space analysis and design.
