Gravitational and Autoregressive Analysis Spatial Diffusion of COVID-19 in Hubei Province, China
Yanguang Chen, Yajing Li, Yuqing Long +1
The spatial diffusion of epidemic disease follows distance decay law in geography, but different diffusion processes may be modeled by different mathematical functions under differ…
Spatial Signal Analysis based on Wave-Spectral Fractal Scaling: A Case of Urban Street Networks
Yanguang Chen, Yuqing Long
For a long time, many methods are developed to make temporal signal analyses based on time series. However, for geographical systems, spatial signal analyses are as important as te…
Multifractal scaling analyses of the spatial diffusion pattern of COVID-19 pandemic in Chinese mainland
Yuqing Long, Yanguang Chen, Yajing Li
Revealing spatiotemporal evolution regularity in the spatial diffusion of epidemics is helpful for preventing and controlling the spread of epidemics. Based on the real-time COVID-…
Multifractal scaling analyses of urban street network structure: the cases of twelve megacities in China
Yuqing Long, Yanguang Chen
Traffic networks have been proved to be fractal systems. However, previous studies mainly focused on monofractal networks, while complex systems are of multifractal structure. This…
Defining Urban Boundaries by Characteristic Scales
Yanguang Chen, Jiejing Wang, Yuqing Long +3
Defining an objective boundary for a city is a difficult problem, which remains to be solved by an effective method. Recent years, new methods for identifying urban boundary have b…
Exploring the relationship between urbanization and Ikization
Lv Ye, Yanguang Chen
The phenomenon of Iks was first found by anthropologists and biologists, but it is actually a problem of human geography. However, it has not yet drawn extensive attention of geogr…
