Methane and nitrous oxide fluxes from four tundra ecotopes in Ny-lesund of the High Arctic被引量:1
《Journal of Environmental Sciences》2014年第7期1403-1410,共8页Qingqing Chen Renbin Zhu Qing Wang Hua Xu 
supported by the National Natural Science Foundation of China (Nos. 41176171, 41076124);Specialized Research Fund for the Doctoral Program of Higher Education (No. 20123402110026).
During the summers of 2008 and 2009, net methane(CH4) and nitrous oxide(N2O) fluxes were investigated from 4 tundra ecotopes: normal lowland tundra(LT), bird sanctuary tundra(BT), the tundra in an abandoned c...
