在过去的几十年里，梯度模式分析已被有效地用于表征世界各地的城市人口分布的空间格局。这些研究大多只侧重于个别案例研究或有限的城市。然而，测量、分析和理解城市人口分布的复杂空间模式需要超越城市孤立案例的比较研究。因此，本研究通过地理空间方法，使用LandScan™ 2013年的人口数据，分析了世界50个最大城市沿城市中心梯度距离的人口分布的空间格局。对于每个城市，城市中心是根据地标地点划分的，人口密度是使用从城市中心开始的同心缓冲区计算的。研究主要确定了沿着距市中心梯度距离的人口分布的五种基本空间格局。此外，研究还对比了发展中国家和发达国家城市之间的人口分布空间格局。
In past decades, gradient pattern analysis has been used effectively to characterize the spatial pattern of population distribution in cities worldwide. Most of these studies have focused only on individual case studies or a limited number of cities. However, measuring, analyzing, and understanding complex spatial patterns of city population distribution requires comparative studies that extend beyond the isolated case of cities. Therefore, the present study analyses the spatial pattern of population distribution along the gradient distance from the city centers of the world’s 50 largest cities using LandScan™ population data from 2013 through a geospatial approach. For each city, the city center was demarcated based on a landmark place, and population density was calculated using concentric buffers from the city center. The study mainly identified five basic spatial patterns of population distribution along the gradient distance to the city center. In addition, the study contrasted the spatial patterns of population distribution between cities in developing and developed countries.
