Objective This study aims to quantitatively reveal the dynamic correlation characteristics between landscape pattern and habitat quality in the Yellow River Basin from 1980 to 2023, thereby providing a scientific basis for constructing a regional ecological security barrier. Methods Based on multi-period land use data, regional landscape pattern indices were calculated and habitat quality was evaluated. The statistical relationships were analyzed using Spearman′s rank correlation and linear regression, and the spatial correlation characteristics were revealed using bivariate spatial autocorrelation. Results (1) The landscape pattern showed a phased evolution from 1980 to 2023. From 1980 to 1995, it tended towards regularization and enhanced connectivity, while from 1995 to 2023, it shifted towards heterogeneity and fragmentation. Spatially, it presented a spatial pattern of “high fragmentation in the central and eastern parts, and low disturbance in the west”. (2) The average value of habitat quality showed a stepwise decline, with a slight overall decrease and significant spatial heterogeneity, showing a pattern of “high in the west and low in the east”. The area of low-quality habitats expanded to 3.76%, while that of high-quality habitats shrank to 22.45%. (3) A significant correlation was observed between landscape pattern and habitat quality. Habitat quality showed a significant positive correlation with CONTAG and LPI, and a strong negative correlation with PD, LSI, and SHEI. Spatial autocorrelation revealed a pattern of “high connectivity-high quality” in the west and “high fragmentation-low quality” in the east. Conclusion The overall habitat quality in the Yellow River Basin has been continuously degrading. Controlling landscape fragmentation in the central and eastern regions and enhancing the connectivity of core patches are key pathways for improving habitat quality in the Yellow River Basin.
