外文摘要：The variation in plant biomass and nitrogen (N) removal capacity with species composition was studied in two constructed wetlands. Findings indicated that increased species compositions had a positive influence on plant biomass and a negative effect on the inorganic N concentrations in substrate and substrate solution (effluent). Elevated N concentrations enhanced the effects of species compositions on plant biomass. The Cyperus alternifolius+ Arundo donax mixture produced the largest plant biomass and the smallest inorganic N concentrations in substrate. The Cyperus alternifolius+ Coix lacryma-jobi + Arundo donax and the Cyperus alternifolius+ Coix lacryma-jobi + Lythrum salicaria + Arundo donax mixtures produced the largest plant biomass under high N condition (146 g N m(-2) yr(-1)). In general, the three-and four-species compositions produced the largest plant biomass and the smallest inorganic N concentrations in substrate and effluent. It suggests that plant mixtures are useful in increasing plant biomass and the wastewater N removal capacity.
