Abstract The rapid uplift of the Qinghai-Tibet Plateau has changed the morphologic units, the tectonic frameworks, the rivers strike, the Asian monsoon and the climate. On the basis of the survey and monitoring results of eco-geological environment and from the angle of the uplift of the Qinghai-Tibet Plateau, this paper systematically describes the eco-geological environment features, the response of eco-geological environment and its regularity in the Qinghai-Tibet Plateau. The results show that the geological environment of the Qinghai-Tibet Plateau is the foundation controlling the formation, development and evolution of ecological environment of the Qinghai-Tibet Plateau and its surrounding areas. The rapid uplift of the Qinghai-Tibet Plateau has provided external factors for modern glaciers, desertification and geological disasters. Besides, the climatic environment of the Qinghai-Tibet Plateau is the power source of ecological environment change in China. Human activities have played a catalytic role in ecological environment change in the Qinghai-Tibet Plateau and its surrounding areas.
