This paper introduces urban land teleconnections as a conceptual framework that explicitly links land changes to underlying urbanization dynamics. We illustrate how three key themes that are currently addressed separately in the urban sustainability and land change literatures can lead to incorrect conclusions and misleading results when they are not examined jointly: the traditional system of land classification that is based on discrete categories and reinforces the false idea of a rural-urban dichotomy; the spatial quantification of land change that is based on place-based relationships, ignoring the connections between distant places, especially between urban functions and rural land uses; and the implicit assumptions about path dependency and sequential land changes that underlie current conceptualizations of land transitions. We then examine several environmental "grand challenges" and discuss how urban land teleconnections could help research communities frame scientific inquiries. Finally, we point to existing analytical approaches that can be used to advance development and application of the concept.
本文提出城市土地联系的概念框架，明确将土地变化与城市发展的动态联系起来。本文通过三个关键主题的例证，说明了目前在城市可持续性和土地变化文献中分别讨论的主题，如果不进行联合研究，可能会导致错误的结论和误导性结果：传统的土地分类系统基于离散类别，强化了城乡二分法的错误观念；土地变化的空间量化基于基于地点的关系，忽略了遥远地区之间的联系，尤其是城市功能与农村土地利用之间的联系；以及当前土地转变概念所隐含的关于路径依赖和顺序土地变化的假设。然后，我们研究了几个环境“重大挑战”，并讨论了城市土地联系如何帮助研究界构建科学研究。最后，我们指出了可以用来推进该概念的发展和应用的现有分析方法。
