    • China's changing landscape during the 1990s : large-scale land transformations estimated with satellite data 

      Liu, Jiyuan; Tian, Hanqin; Liu, Mingliang; Zhuang, Dafang; Melillo, Jerry M.; Zhang, Zengxiang (American Geophysical Union, 2005-01-27)
      Land-cover changes in China are being powered by demand for food for its growing population and by the nation's transition from a largely rural society to one in which more than half of its people are expected to live in ...
    • China's terrestrial carbon balance : contributions from multiple global change factors 

      Tian, Hanqin; Melillo, Jerry M.; Lu, Chaoqun; Kicklighter, David W.; Liu, Mingliang; Ren, Wei; Xu, Xiaofeng; Chen, Guangsheng; Zhang, Chi; Pan, Shufen; Liu, Jiyuan; Running, Steven W. (American Geophysical Union, 2011-03-31)
      The magnitude, spatial, and temporal patterns of the terrestrial carbon sink and the underlying mechanisms remain uncertain and need to be investigated. China is important in determining the global carbon balance in terms ...
    • Effects of tropospheric ozone pollution on net primary productivity and carbon storage in terrestrial ecosystems of China 

      Ren, Wei; Tian, Hanqin; Liu, Mingliang; Zhang, Chi; Chen, Guangsheng; Pan, Shufen; Felzer, Benjamin S.; Xu, Xiaofeng (American Geophysical Union, 2007-11-17)
      We investigated the potential effects of elevated ozone (O3) along with climate variability, increasing CO2, and land use change on net primary productivity (NPP) and carbon storage in China's terrestrial ecosystems for ...
    • Food benefit and climate warming potential of nitrogen fertilizer uses in China 

      Tian, Hanqin; Lu, Chaoqun; Melillo, Jerry M.; Ren, Wei; Huang, Yao; Xu, Xiaofeng; Liu, Mingliang; Zhang, Chi; Chen, Guangsheng; Pan, Shufen; Liu, Jiyuan; Reilly, John M. (IOP Publishing, 2012-10-31)
      Chemical nitrogen (N) fertilizer has long been used to help meet the increasing food demands in China, the top N fertilizer consumer in the world. Growing concerns have been raised on the impacts of N fertilizer uses on ...
    • Net exchanges of CO2, CH4, and N2O between China's terrestrial ecosystems and the atmosphere and their contributions to global climate warming 

      Tian, Hanqin; Xu, Xiaofeng; Lu, Chaoqun; Liu, Mingliang; Ren, Wei; Chen, Guangsheng; Melillo, Jerry M.; Liu, Jiyuan (American Geophysical Union, 2011-05-13)
      China's terrestrial ecosystems have been recognized as an atmospheric CO2 sink; however, it is uncertain whether this sink can alleviate global warming given the fluxes of CH4 and N2O. In this study, we used a process-based ...
    • Pattern and variation of C:N:P ratios in China’s soils : a synthesis of observational data 

      Tian, Hanqin; Chen, Guangsheng; Zhang, Chi; Melillo, Jerry M.; Hall, Charles A. S. (2009-09-01)
      Inspired by previous studies that have indicated consistent or even well-constrained relationships among carbon (C), nitrogen (N) and phosphorus (P) in soils, we have endeavored to explore general soil C:N:P ratios in ...
    • Spatial and temporal patterns of carbon emissions from forest fires in China from 1950 to 2000 

      Lu, Aifeng; Tian, Hanqin; Liu, Mingliang; Liu, Jiyuan; Melillo, Jerry M. (American Geophysical Union, 2006-03-11)
      We have estimated the emission of carbon (C) and carbon-containing trace gases including CO2, CO, CH4, and NMHC (nonmethane hydrocarbons) from forest fires in China for the time period from 1950 to 2000 by using a combination ...
    • The terrestrial biosphere as a net source of greenhouse gases to the atmosphere 

      Tian, Hanqin; Lu, Chaoqun; Ciais, Philippe; Michalak, Anna M.; Canadell, Josep G.; Saikawa, Eri; Huntzinger, Deborah N.; Gurney, Kevin R.; Sitch, Stephen; Zhang, Bowen; Yang, Jia; Bousquet, Philippe; Bruhwiler, Lori; Chen, Guangsheng; Dlugokencky, Edward J.; Friedlingstein, Pierre; Melillo, Jerry M.; Pan, Shufen; Poulter, Benjamin; Prinn, Ronald G.; Saunois, Marielle; Schwalm, Christopher R.; Wofsy, Steven C. (2015-12-21)
      The terrestrial biosphere can release or absorb the greenhouse gases, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and therefore plays an important role in regulating atmospheric composition and climate1. ...
