简介：都市化的过程被人的常规运动形成。它在一个城市里产出不同功能的地区，例如居住地区和商业地区。因而，在那里存在在人的活动性模式和城市之间的一个靠近的连接是地区。然而，收集能精确捕获在个人的运动和地区性的功能之间的内在的关系的大规模社会宽的数据不是容易的。因此，我们为理解人的活动性的基本模式的知识仍然是有限的。以便在一个城市里发现不同区域的功能，我们建议一种亲密关系在这份报纸基于方法。亲密关系是为在一个复杂网络测量二个连接节点的关联的一个最近介绍的度量标准。建议模型由经由相对的熵测量用户的到达/离开分发组织不同功能的地区。除了这，我们也由拿核密度评价(KDE)识别每个功能的地区的紧张方法。最后，一些实验被进行与大规模真实数据集评估我们的方法，它从一个月的一个时期由300万个蜂窝电话用户的记录组成。我们在活动性模式和地区性的函数之间的相互作用上的调查结果能高效地捕获城市动力学并且为城市的规划者提供珍贵引用。
