As global climate change intensifies, arid land ecosystems face increasing challenges. Vegetation, a key indicator of variation, is highly responsive to meteorological factors such as temperature (Tem), precipitation (Pre), and soil moisture (SM). Understanding how fractional vegetation cover (FVC) responds in regions critical for mitigating its impacts. This study utilizes MOD13Q1-NDVI data from 2000 2022, alongside corresponding Tem, Pre, SM data, explore the dynamics underlying mechanisms FVC context change. The results reveal that both human activities exacerbate degradation, underscoring vulnerability. A strong correlation between Tem Pre suggests these significantly influence variability. In conclusion, lower reaches Heihe River shaped by complex interplay SM, activities. findings provide scientific basis decision-making support ecological conservation water resource management River, aiding development more effective strategies address future
