Code for the paper "Does residential segregation align with urban barriers?"

This code is used for computing the results of the paper "Does residential segregation align with urban barriers?". <br>This code quantifies the spatial alignment between residential segregation patterns and urban fragmentation across 520 European cities using a Monte Carlo approach. The analysis generates synthetic urban fragmentation patterns using Voronoi tessellation and compares observed spatial overlap against null distributions to test whether urban barriers (railways, motorways, waterways) act as social frontiers more than expected by chance.

本代码用于计算论文《居住隔离与城市壁垒是否契合？》的相关结果。本代码采用蒙特卡洛（Monte Carlo）方法，对520个欧洲城市的居住隔离格局与城市碎片化程度之间的空间契合度进行量化。本次分析利用泰森多边形（Voronoi tessellation）生成模拟的城市碎片化格局，将观测得到的空间重叠度与零分布进行对比，以此检验铁路、高速公路、航道这类城市壁垒是否比随机概率下更易充当社会边界。
