Taking Nanning City as an example, the evaluation system of land intensive use was established based on PSR model, and the entropy weight method was used to calculate the weight of various indicators to evaluate the situation of land intensive use in Nanning City quantitatively. The results show that the level of land intensive use in Nanning continues to improve from 2012 to 2021, the land pressure system decreases first and then rises, the land state system increases, the land response state is relatively stable, and the coordination degree of land intensive use is also in a stable state. The population density of Nanning City is increasing, and the land pressure is rising, but the growth rate of construction land is decreasing gradually, which indicates that the expansion trend of construction land in Nanning City is obviously improved.
