The main causes of habitat conversion, degradation, and fragmentation—all which add to the loss in biodiversity—are human activities, such as urbanization farmland reclamation. In order inform scientific land management biodiversity conservation strategies and, therefore, advance sustainable development, it is imperative evaluate effects land-use changes on biodiversity, especially areas with high biodiversity. Using data from five future scenarios under various Shared Socioeconomic Pathways (SSPs) Representative Concentration (RCPs), this study systematically assesses characteristics landscape pattern southwest China by 2050. This builds a comprehensive index forecasts trends species richness quality using models like Fragstats InVEST overall research yielded subsequent conclusions: (1) Grasslands woods will continue be primary uses future. But amount grassland expected decrease 11,521 102,832 km2, amounts wasteland urban area are increase 8130 16,293 km2 4028 19,677 respectively. Furthermore, anticipated that metropolitan see an fragmentation shape complexity, whereas forests wastelands these aspects. (2) China, there synergistic relationship between quality, both still at relatively levels. terms percentage regions categorized outstanding good range 71.63% 74.33% 70.13% 75.83%, environmental circumstances for survival worsen comparison 2020, notwithstanding Western Sichuan, southern Guizhou, western Yunnan home most high-habitat-quality species-richness areas, while plateau majority lower scoring areas. (3) (89.84% 94.29%) forecast undergo little change spatial distribution general ecological environment predicted stay favorable. Except SSP1-RCP2.6 scenario, however, region declining exceed those increasing projected decline 1.0562% 5.2491% index. These results underscore major obstacles area, highlighting need fortify macro-level management, put into practice efficient regional plans, incorporate traditional knowledge save
