The advent of geolocated information and communication technologies opens the possibility of exploring how people use space in cities, bringing an important new tool for urban scientists and planners, especially for regions where data are scarce or not available. Here we apply a functional network approach to determine land use patterns from mobile phone records. The versatility of the method allows us to run a systematic comparison between Spanish cities of various sizes. The method detects four major land use types that correspond to different temporal patterns. The proportion of these types, their spatial organization and scaling show a strong similarity between all cities that breaks down at a very local scale, where land use mixing is specific to each urban area. Finally, we introduce a model inspired by Schelling's segregation, able to explain and reproduce these results with simple interaction rules between different land uses.
地理位置信息和通信技术的出现为探索人们在城市中如何利用空间提供了可能，为城市科学家和规划者带来了一个重要的新工具，尤其是在数据稀缺或不可用的地区。在这里，我们应用功能网络方法从手机记录中确定土地利用模式。该方法的多功能性允许我们在不同规模的西班牙城市之间进行系统比较。该方法检测到四种主要的土地利用类型，它们对应于不同的时间模式。这些类型的比例、它们的空间组织和规模在所有城市之间表现出很强的相似性，这种相似性在非常局部的尺度上被打破，在这个尺度上，每种城市区域的土地利用混合都是特定的。最后，我们引入了一个受谢林隔离启发的模型，该模型能够用不同土地利用之间的简单相互作用规则来解释和再现这些结果。
