Abstract: The Tibetan Plateau hosts the world’s highest natural treelines, being potentially sensitive to climate change. In the last 10 years, Dr. Liang has been focusing on dendroecology of alpine treeline on the Tibetan Plateau. His research aims to answer these questions: what is the physiological mechanism for alpine treeline formation based on nature treelines on the Tibetan Plateau? Whether are there significant changes in structures and patterns of alpine treeline?
