As a critical ecological functional area in China, the Chishui River Basin plays a vital role in maintaining land ecological security and promoting agricultural and rural development. This study establishes an evaluation index system for land ecological security and rural revitalization, and applies the coupling coordination model to quantitatively analyze the interactive characteristics between ecological security and rural revitalization in the basin from 2012 to 2022. The results indicate a general upward trend in both land ecological security and rural revitalization levels over the study period. The degree of coupling coordination has shown a steady growth trajectory, albeit with spatial heterogeneity across regions, presenting a distinct "high–medium–low" gradient pattern from east to west. These findings offer valuable insights for formulating policies aimed at achieving coordinated and sustainable development in the Chishui River Basin.
