Abstract: Aims CO2, CH4 and N2O are important greenhouse gases, and they mainly come from soils in forest ecosystems. Our objective was to analyze the effects of removal of the understory and addition of Cassia alata on soil CO2, CH4 and N2O emissions in Heshan Hilly Land Interdisciplinary Experimental Station, Chinese Academy of Sciences, Guangdong Province, China.
Methods CO2, CH4 and N2O fluxes in a Eucalyptus urophylla plantation were measured in situ using the static chamber technique from June 2007 to May 2008.
Important findings CO2 fluxes stayed at a relatively high level during the rainy season and a lower level in the dry season, while CH4 and N2O fluxes varied widely in the rainy season and were stable in the dry season. Peak values of CO2 and CH4 appeared in the rainy season, while the peak value of N2O flux was in the dry season (December). The E. urophylla plantation soil was a sink or source for CH4 while consistently a source for CO2 and N2O. Understory removal and C. alata addition significantly enhanced CO2 (p<0.01) and N2O fluxes (p<0.01), while decreasing or increasing CH4 fluxes under the same treatments. Results indicated that soil temperature, soil moisture, NO3-N and microbial biomass carbon (MBC) might be important variables for soil CO2, CH4 and N2O fluxes.
