Effect of plant species richness on the methane (CH4) flux was investigated in vertical flow microcosms fed with the modified Hoagland solution. The CH4 flux increased significantly with the plant species richness (Linear regression analysis, r2 = 0.203, P = 0.010), with an average range from 1.59 to 4.30 mg m−2 d−1. Above-ground plant biomass followed the CH4 flux trend with the plant species richness (r2 = 0.108, P = 0.023), but both methanogenic number and activity decreased to different extents with the plant species richness (r2 = 0.103, P = 0.023; r2 = 0.020, P = 0.337), respectively. Accordingly, the present study highlights the significance of plant species diversity and its biomass production in manipulating the CH4 flux in the constructed wetlands.
