Understanding the impact of climate change and human activities on vegetation dynamics is crucial for ecosystem management. Employing Residual Trend method integrating Normalized Difference Vegetation Index (NDVI) data with land use/cover, this study assesses impacts across China from 2000 to 2018. The findings indicate a consistent upward trend China's Growing Season NDVI (GSN), averaging rate 0.0032/yr. Human are primary drivers change, contributing 82.47% GSN in China, while accounts 17.53%. effect showed considerable variation different river basins, Huaihe River Basin experiencing highest (93.53%) Continental lowest (76.27%). Conversely, experienced greatest (23.73%), compared minimal influence (6.47%). results offer contribution rates each type changed unchanged use, persistent forestland, grassland, cropland, grassland forest conversion 28.65%, 22.09%, 13.76%, 4.61%, respectively. Persistent forestland emerges as most efficacious use facilitating restoration. Within forestlands Yangtze, Pearl, Southeast Basins, accounted 26.99%, 42.18%, 43.50% alterations, These provide scientific basis formulating effective management protection strategies.
