Design Example of Catalyst Effect Analysis with Topological Graphing

Urban catalyst theory is based on the excavation of phenomenon "mutual stimulation elements", designing and amplifying synergistic effect between elements, that is, effect. In this paper, topological analysis framework dotted-line relationship physical space introduced, it found topology has distinct characteristics. This a minor innovation in understanding urban theory. A case illustrates full process transforming elements produce from "grand-centered structure" to "polycentric "distributed structure". Starting classic case, paper reproduces further shows occurrence perspective topology, uses more cases show design different types effects, providing new ideas references for future effects situations.
