Using Built Environment to Simulate the Spatial Distribution of the Working and Resident Population in Mega-cities:A Case Study of Chongqing Central City
A method was proposed for spatial distribution analysis of urban population in the central urban area of Chongqing city,aiming to formulate scientific and rational schemes for population dispersion.This method was based on the built environment and in-volves the following steps:firstly,acquiring built environment variables using multi-source geographical data;secondly,calculating the grey correlation between built environment variables and residential population,thereby filtering strongly correlated variables;and final-ly,training a random forest model on the selected variables to construct a spatial model of residential population distribution.The re-sults indicate that this method achieves a high fitting accuracy for residential population spatialization,effectively to simulate urban resi-dential population distribution and accurately understand the spatial distribution of residential population.
