The main research topics of the RCTGCE include (i) how the tectonics and surface processes shaped the landscape of tectonically active regions (e.g., the Tibetan Plateau) at time scales ranging from decades to millions of years, (ii) the role of tectonically uplifted regions as a carbon source (via volcanic and tectonic CO2 emissions) or sink (i.e., silicate weathering) in global climate change, and (iii) the response of the ecosystem to climate and environmental changes. Through the above studies, we hope to gain a better understanding of how the Earth’s surface has evolved from the perspective of interactions between tectonics, geomorphy, climate and the ecosystem.
