摘　　要：作为地球的“第三极”,青藏高原越来越受到世界的关注,本文就青藏高原的环境效应问题进行了研究和探讨。青藏高原的隆起和抬升,形成了其自身独特的自然环境特征,促成了独特的高原季风系统,造就了中国现代季风格局,影响着全球气候的变化和亚洲植被格局的分布,导致了亚洲干旱地带的北移和植被地带的不对称分布,形成了世界上著名的高原地带性植被格局。对中国东部、西北干旱区、亚洲的气候和植被格局乃至全球气候变化都具有深刻的影响。The Tibetan Plateau, well-known as the 'roof of the world' and the 'third polar of the earth', is the youngest and most immense plateau on earth. This paper summarizes and analyzes research results and conclusions with respect to the environmental effects of the Plateau. The plateau shows particular environmental features, such as high cold climate and unique ecological patterns known as 'Tibetan zonation'. It also has deep influence on the climate and vegetation patterns of East Monsoon China, Northwest Arid China, the Asia, and even the whole world. The climatic effects of the Plateau include its distinct plateau monsoon system and the formation of modern monsoon system of China. The plateau is characterized by frequent natural disasters, e.g., forest degradation, soil erosion, earthquake, landslide, debris flow, etc. Huamn impacts on the plateau could not be negleated, although they are not very strong.
