Abstract:: In order to explore the influence of human activities on the ecosystem and contribution，based on the normalized difference vegetation index(NDVI)，meteorological data and social economic data of Qinghai-Tibet Plateau region in 2000—2018，the change trend analysis and residual analysis，methods of relative importance were used to analyze the vegetation change pattern in growing season of the Qinghai-Tibetan Plateau within nearly 19 years，and the effects of different types of human interference on the change of the gene were quantified. The results showed that:(1)from 2000 to 2018，NDVI increased in Qinghai-Tibetan plateau;(2)the area where human activities promoted vegetation cover accounted for 61.16% of the total area，and the area where human activities destroyed vegetation cover accounted for 38.84% of the total area;(3)the vegetation change in Haixi Prefecture，Haibei Prefecture and Nagqu City was dominated by GDP₁; the vegetation change in Yushu Prefecture was mainly caused by GDP₂; the vegetation change in Huangnanzhou，Qamdo and Nagqu was dominated by GDP₃; the vegetation change in Haibei Prefecture and Qamdo City was mainly caused by grazing intensity; the vegetation change in Haina Prefecture was mainly dominated by population urbanization; in Xining，Lhasa and Guoluo area，the contribution rate of vegetation change of the five indexes is similar. The social and economic development in different areas of the vegetation ecosystem depend on the strength of different，in the present and the future maintenance of regional ecological system and social system under the goal of sustainable development，according to the development of different regions should adopt corresponding measures，in order to realize the regional ecological environmental benefit，economic benefit and social benefit maximization.
