Head of the Group: Dr. FAN Zexin
Tree Ring and Environmental Change Group, set up since June 2012, is a Young Scientist Group of Xishuangbanna Tropical Botanical Garden (XTBG), Chinese Academy of Sciences (CAS). This group focuses on environmental change in the tropical, subtropical regions of southwestern China. By combining dendrochronology, tree ecophysiology, and climatic statistics, we focus on reconstructing regional climate change during the past centuries; investigating growth-climate responses of tropical/sub-tropical tree species; detecting physiological adaptation of tropical plants to simulated environmental change (i.e. CO2 enrichment, global warming); modelling vegetation thermal response based on thermodynamics, energy balance and radiation balance.
Tropical dendroecology and dendroclimatology
By using dendrochronology methods, we attempt to reconstruct regional climatic change of tropical Asia during the past centuries, study growth responses of tropical and subtropical tree species to climatic and environmental changes, as well as the physiological adaptation of tree growth to climate conditions.
Plant thermal response and their ecological significance
Based on thermodynamics, energy balance and radiation balance, we aim to reveal the relationship between vegetation thermal response and vegetation development and health on the scale of community and landscape, establish a thermodynamic index system to quantitatively evaluate ecosystem function.
Ecophysiological responses of tropical plants to simulated environmental changes
Taking advantages of plant ecophysiological techniques, we study photosynthesis, water relations and phenology of functional groups in tropical forests, as well as their physiological responses to simulated environmental changes (i.e. CO2 enrichments, warming experiments).
