Assessment of Topographic Effect on Habitat Quality in Mountainous Area Using InVEST Model

The topographic differentiation patterns of changes in habitat quality are great significance for the scientific formulation environmental protection policies mountainous areas. Here, distribution, changing trends, and effects gradient on were studied using InVEST model, distribution index, Mann–Kendall test. results showed that at p < 0.05 (Z = 1.67), from 2000 to 2020 three types trends (significant decline, non-significant change, significant increase), accounting 22.2%, 41.8%, 36% changes, respectively. Because livelihood structure local residents geological disasters high-elevation areas, this terrain was predominant area showing a decline quality. Thanks consolidation projects natural forest resources, return farmland forest, implementation protecting low-lying topography increase middle position no Based analysis, ecological management measures high-, medium-, low-elevation areas suggested.
