Habitat Quality Assessment under the Change of Vegetation Coverage in the Tumen River Cross-Border Basin

The continuous deterioration of terrestrial ecosystems has led to the destruction many biological habitats in recent years. Tumen River cross-border basin, an important habitat, is also affected by this changing situation. Assessing habitat quality (HQ) crucial for restoring and protecting habitats, vegetation plays a significant role process. In study, we used geographical detector (GD) extract fraction coverage (FVC) features quantify contribution driving factors. By coupling cover land use data, assessed HQ. Our findings reveal declining trend FVC from 2000 2020, which mainly assumed spatial pattern inclined northeast southwest southeast. Human activities natural factors interacted cause these changes FVC, with human having more impact. Vegetation decline basin’s HQ index. This study highlights provides relevant scientific reference optimizing evaluation basin promoting sustainable development regional ecology.
