Current Research Interests

Stable isotope ecology is of particular interest to me, and development of optical isotope techniques has provided a set of interesting tools for understanding of CO2 and water vapor exchange in the soil-plant-atmosphere continuum. The behavior of kinetic fractionation at canopy scales or isotopic non-steady state leaf transpiration can be observed using high frequency and continuous isotope measurements. We have already obtained 3-year hydrogen, oxygen and carbon stable isotopes data with Off-Axis Integrated Cavity Output Spectroscopy instrument at the Xiaolangdi forest ecosystem research station, which belongs to the Chinese forest ecosystem research network (CFERN). Although I had summarized the preliminary results in the process of study, the interesting data implied that more complex scientific problems need us to further understand.
