In research and development on the ethical and environmentally friendly utilisation of land resources, land ecological safety is currently a hot topic. The entropy weight TOPSIS model and the dark correlation model were used to assess and analyse the level of ecological safety of land resources in North China from 2012 to 2021 based on the DPSIRM (Driving force-Pressure-State-Impact-Response-Management) conceptual framework. The findings show that, firstly, there has been positive overall development and a general rising trend in North China's ecological safety exponents of land resources throughout the study session. The ecological safety state of land resources exhibits three distinct stages: fundamental flatness, major growth, and slight reduction. Second, there are notable differences in the ESLR between North China's provinces (municipalities), with Tianjin (0.4495) in a more precarious situation and Hebei (0.5966) in the ideal position. Third, North China's provinces (municipalities) are greatly influenced by geographical area and resource condition. Fourth, the land resource pressure indicator has the strongest correlation with the state of ESLR in North China.
