摘要 非正式的城市土地扩张是通过各种社会和政治交易产生的，但捕获这些交易的“像素化”数据通常无法获得。理解非正规城市化需要将非正规住区的空间模式与正规增长区分开来，将这些模式与产生它们的社会交易联系起来，并评估不同住区类型的社会和环境结果。展示不同的城市空间模式和社会制度过程之间的因果关系需要城市变化的高分辨率时空时间序列数据和对引起这些模式的社会交易的洞察。我们展示了一个例子，将非正式城市扩张的不同空间模式与墨西哥城产生的制度进程联系起来。这里提出的方法可以适用于各种情况，有可能改善快速城市化的南半球的土地预测模型，其特点是高度非正式性。最后，我们提出了一个研究议程，旨在识别、预测和评估非正式的城市扩张模式。
ABSTRACT Informal urban land expansion is produced through a diversity of social and political transactions, yet ‘pixelizable’ data capturing these transactions is commonly unavailable. Understanding informal urbanization entails differentiating spatial patterns of informal settlement from formal growth, associating such patterns with the social transactions that produce them, and evaluating the social and environmental outcomes of distinct settlement types. Demonstrating causality between distinct urban spatial patterns and social-institutional processes requires both high-resolution spatial temporal time-series data of urban change and insights into social transactions giving rise to these patterns. We demonstrate an example of linking distinct spatial patterns of informal urban expansion to the institutional processes each engenders in Mexico City. The approach presented here can be applied across cases, potentially improving land projection models in the rapidly urbanizing Global South, characterized by high informality. We conclude with a research agenda to identify, project, and evaluate informal urban expansion patterns.
