Based on the multi-source data of Gaode map POI, population density, land price and digital elevation model, this study explored the spatial-temporal differentiation, influencing factors and over-standard control of residential floor area ratio in Guangzhou from 2012 to 2022 by means of spatial autocorrelation and geographical detector. The results showed that:(1)The city’s residential floor area ratio was high and varied, and had experienced two stages of fluctuation and invisible stability, with a maximum value of 4.0 in 2016 and a minimum value of 2.5 in 2018. (2) On the whole, it showed the characteristics of circle layer decreasing with high concentration in the center and low in the edge, and proportion of over-standard plots accounts was nearly 40%, while the rate of exceeding the standard in the old city was even as high as 84%. (3) The spatial differentiation of residential floor area ratio was affected by multiple factors such as natural environment, built environment, plot attribute and social economy, and land price and population density were the dominant factors.(4)It was suggested to formulate strength zoning scheme, control guidance and adjustment coefficient, implement rigid control and elastic adjustment of residential floor area ratio, and realize the zoning and grading control of residential floor area ratio in Guangzhou.
