Effect of plant presence and species richness on methane flux and its microbial processes in the vertical constructed wetlands

摘要：

　　Constructed wetlands (CWs),a natural alternative to technological methods of wastewater treatment,have been widely used to reduce excessive nutrient loading attributable to human activities over the past decades.However,the production of several GHGs (e.g.,CO2,N2O,and CH4) could mitigate the environmental benefits of nutrient removal in these man-made ecosystems.It was reported that CWs emitted 2-10 times more GHGs than natural wetlands.And CWs,combining natural wetlands and wastewater treatment plants,were regarded as a large potential source of CH4 emission.Hence,CH4 emission from CWs has raised environmental concern.
