This study assesses the impact of climate change and human activities on vegetation dynamics (kNDVI) Qinghai-Tibet Plateau (QTP) between 2000 2022, considering both lag cumulative effects. Given QTP’s high sensitivity to activities, it is imperative understand their effects for sustainable development regional national terrestrial ecosystems. Using MOD13Q1 NDVI activity data, we applied methods such as Sen-MK, effect analysis, improved residual geographical detector analysis. The outcomes were follows. (1) kNDVI QTP showed an overall fluctuating growth trend 2022; regions more significant than degraded regions, with primarily distributed in humid semi-humid areas favorable conditions, arid semi-arid areas; this implies that conditions have a changes QTP. (2) analysis revealed temperature precipitation substantial 0 months 1 month temperature, 2 precipitation, respectively. (3) Improved based positively contributed 66% QTP, suggesting notable positive activities. Geographical indicated that, among different factors affecting changes, explanatory power 2005 2015 ranked X3 (livestock density) > X1 (population X2 (per capita GDP) X4 (artificial afforestation X5 (land use type), 2020, X2. density land type has relatively increased, indicating recent efforts ecological protection restoration including developing artificial forest programs, considerably greening.
