Head of the Group: Prof. Dr. LIU Wenjie
MAJOR FIELD OF RESEARCH:
The major research of EHRG is focused on the mechanisms controlling water and soil processes in relation to environmental variables in tropical and subtropical forests of Yunnan Province, SW China. This includes investigating the hydrological function, manipulation and management of water and soil processes for the tropical and subtropical forests, restoration of degraded lands. We are also interested in the research on water-use strategies and patterns of some plants in tropical or subtropical rainforest and plantations in relation to environment change, by using stable isotopic techniques and TDP method.
LIU Wenjie, Chief Professor, Ph.D., received undergraduate training in Meteorology, Department of Geophysics in Yunnan University from 1987 to 1991, and completed Ph. D. research in Ecology, at the Research Centre for Eco-environmental Sciences, Chinese Academy of Sciences in 2005, and also as a visiting scholar of Bo/Nexfor Watershed Research Centre, University of New Brunswick, Canada in 2000 (funded by the Chinese Academy of Sciences).
