Typological Drift

This book documents the impact of the Chinese culture on the development of city types in China in the past four decades, leading to surprising urban realities that often escape normative urban theories. The book uses the concept of drift, which, together with mutation, adaptation, and migration, contributes to the rudimentary patterns of biological change; drift of phenotypes takes place when chance events randomly terminate some features and allow other features to flourish in ways that are unrelated to other patterns. The Chinese culture has exerted a set of forces that may be seen to have functioned as "unexpected events" in the normative processes of urban change. Through 13 case studies, more than 60 original maps and drawings, and extensive photographic documentation, the book reveals how three "drift triggers" - ten thousand things, figuration, and group action - have altered typological development in Chinese cities in the past four decades.
