Abstract

Methane (CH4) flux was measured by using the Eddy covariance technique in the Dajiuhu Wetland of Shennongjia Forestry District, Hubei Province, China. The seasonal and daily variation of CH4 emissions was investigated, and the correlation of CH4 fluxes with the environmental impact factors were discussed to understand the activity of CH4 flux and the effects of environmental factors including air temperature, soil temperature, photosynthetic photon flux density (PPFD), and rainfall on a wetland ecosystem. The results indicated that CH4 flux was significantly correlated with air temperature and photosynthetic photon flux density (PPFD), which may be the primary driver of controlling peatland CH4 flux.
