This book is intended to introduce CH4 fluxes from wetlands to climate ma—nagers,policy makers，practicing scientists，modellists，advanced undergraduatestudents,beginning graduate students from a wide array of disciplines，such asecologG climatology,geographyj forestry,microbiology,etc．We also provideaccess to the rapidly expanding literature in CH4 fluxes of wetlands in Chinathat contribute to fully understanding of the budget of CH4 fluxes of wetlandsin China and their trends．
