Indo-Asian Collision as a Key Factor in the Formation of Arid Ecosystems in Tibet at Subtropical Latitudes
摘要
Abstract
The paper examines the influence of the Indo-Asian collision on the formation of arid ecosystems covering a vast territory in the subtropics. It has been shown that the rise of the Tibetan Plateau to more than 4000 m above sea level and the rain shadow produced by the Himalayas, Karakoram, and Hindu Kush are the main reason for the lack of moisture over most of Tibet. To characterize the natural zonation of the Qinghai-Tibet Plateau, we used the classification of vegetation zones proposed by D.H.S. Chang (1981). The Indo-Asian collision is seen as an ecological factor (megafactor) primary to the factors generated by collision processes.
