Carbon Cycle in the Changing Arid Land of China

Presents integrative analyses of organic carbon and carbonate in soil and sediment in a typical arid area of China

Demonstrates the significant role of carbonate in the area's carbon sequestration

Uses a stable carbon isotope to quantify different carbon sources

Features comprehensive analyses of carbon accumulation in response to changes in climate and land use

Dr. Xiujun Wang is a professor and chief scientist at the College of Global Change and Earth System Science, Beijing Normal University. She earned a Ph. D. in soil biochemistry (Melbourne University) and Ph. D. in ocean biogeochemistry (University of Tasmania). She was a principal investigator for NASA carbon projects at the University of Maryland during 2005-2013. Her research focuses on the carbon cycle in soils and sediments of north China. Her main accomplishments include the assessment of accumulation rate of carbonate in north China's cropland. She was the president of Biogeoscience Section, Asia-Oceania Geosciences Society during 2014-2016.
