【 摘 要 】

To find the effects of emerged plant on soil methane (CH4) emission and nitrogen content in constructed wetland, we constructed the constructed wetland microcosms with 3 treatments through 2 emerged plants (Typha orientalis and Phragmites australis). Results showed that soil CH4 flux have no different (2.0, 2.4, 2.5 mg m-2 d-1, P > 0.05), but soil nitrogen contents and microbial biomass nitrogen were significantly different (P0.05). As total plant biomass in the constructed wetlands planted with Typha orientalis (P
