Exploring the intellectual heritage of urban geography in North America (UGNA) is a valuable but daunting challenge. One practical way is to mine the written narratives about its key figures and to map the pattern of their interconnections within a historical and institutional context. Urban Geography in America, 1950–2000: Paradigms and Personalities, a book edited by Berry and Wheeler, permits such an approach. In this book, twenty-five authors primarily documented their study, research, and career experiences. Using the ties among these authors along with those who influenced their research, this article discovers, maps, and interprets the interconnections among notable U.S. urban geographers. These ties were constructed as a social network, and network analysis techniques were applied to examine the structure of the community as well as the evolution of the discipline. This analysis presents a particular view on the roles that individuals, programs, and periods played in the development of twentieth-century UGNA. Explicitly mapping the UGNA community helps geography students and scholars better understand the discipline’s intellectual heritage, historical landscape, and evolutionary trajectory.

探索北美城市地理学 (UGNA) 的知识遗产是一项宝贵但艰巨的挑战。一种实用的方法是挖掘关于其关键人物的书面叙述，并在历史和制度背景下绘制它们相互关联的模式。美国城市地理学，1950-2000：范式和个性由 Berry 和 Wheeler 编辑的一本书允许采用这种方法。在本书中，25 位作者主要记录了他们的学习、研究和职业经历。利用这些作者之间的联系以及影响他们研究的人，本文发现、绘制和解释了著名的美国城市地理学家之间的相互联系。这些联系被构建为一个社交网络，并应用网络分析技术来检查社区的结构以及学科的演变。该分析对个人、计划和时期在 20 世纪 UGNA 的发展中所起的作用提出了特殊的看法。明确地绘制 UGNA 社区有助于地理学学生和学者更好地了解该学科的知识遗产、历史景观、
