In the early part of the twentieth century, South African cities were segregated in accordance with British city planning concepts that embodied the belief that social order can be manipulated through the urban form. This paper surveys the history of South African planning practices to understand the spread of segregation policies and practices. Whereas scholars tend to agree that the apartheid city (post−1948) is a more highly organized and structured version of the colonial city (pre−1910), the literature lacks consensus on the development of the segregated city (1910−1948) within South Africa. How did concepts of segregation circulate and why was it implemented with such consistency? Accordingly, this paper employs concepts of policy mobilities to trace historical configurations in South Africa to international influences. The focus on the circuits of knowledge explains how concepts and designs transplanted from elsewhere helped create the form of South African cities today. Understanding the movement of planning ideas through policy mobilities furthers geographical understandings of historical circulation processes, the role of the local actors, and policy mobilities failure. This history of learning also challenges the assumption that South African cities are unique and in so doing opens the doors for knowledge sharing between postcolonial cities.

从大都市向殖民地传播规划思想：通过政策动员了解南非的偏僻城市

在20世纪初期，南非的城市按照英国的城市规划概念进行了隔离，这些概念体现了人们的信念，即可以通过城市形式来操纵社会秩序。本文调查了南非规划实践的历史，以了解隔离政策和实践的传播。尽管学者们倾向于认为种族隔离城市（1948年后）是殖民城市（1910年前）的高度组织化和结构化的版本，但文献对南部偏远城市（1910-1948年）的发展缺乏共识非洲。隔离的概念是如何传播的，为什么要以这种一致性来实施？因此，本文采用了政策动员的概念，以追溯南非在国际影响下的历史形态。对知识循环的关注解释了从其他地方移植来的概念和设计如何帮助创造了当今南非城市的形式。通过政策动员了解规划思想的运动，可以进一步了解历史流通过程，地方行为者的作用以及政策动员失败的地域。这种学习历史也挑战了南非城市独特的假设，从而为后殖民城市之间的知识共享打开了大门。和政策动员失败。这种学习历史也挑战了南非城市独特的假设，从而为后殖民城市之间的知识共享打开了大门。和政策动员失败。这种学习历史也挑战了南非城市独特的假设，从而为后殖民城市之间的知识共享打开了大门。
