研究方向

The researches focus on the transporting and cycling behaviors of inorganic chemical elementsand their isotopes, released by the natural and artificial processes, and theirimpacts on the ecosystem. Based on carbon (δ13C), strontium (87Sr/86Sr), sulfur (δ34SSO4 and δ18OSO4), nitrogen (δ15NNO3and δ18ONO3) and other stable isotopes,all the studies are to reveal the variation regularities of major inorganicions (sulfate and nitrate etc.) in groundwater, surface water (river, lake, cascadereservoir), rainwater and aerosol, and quantify the percentage of the impactcaused by the natural and artificial processes respectively on the changes of eco-environmentalquality. Now, 

1. Biogeochemicalcycle of nutrient elements (N, P, Si) within cascade reservoirs.
2. Isotopic tracing study on the sources, transformation, andtransport processes of urban aerosol.
