InVEST Model and Landscape Indices Reveal Habitat Quality Degradation From Land Use Changes in South China

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Evaluated the habitat quality changes in Hunan Province from 2000 to 2023. Applying landscape index to evaluate the habitat quality changes. Quantified the contribution of different land use and land cover change (LULC) changes to habitat quality. Spatial correlation is used to analyze the relationship between LULC and habitat quality.
