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.
