摘 要 ：实验通过建立不同模式的小型湿地系统研究了不同基质和不同的植物组合对人工湿地净化效率和效率稳定性的影响。结果表明，种植植物的湿地系统比没有植物的湿地系统净化效率高，沙土混合基质比卵石基质净化效率高；旱伞草和美人蕉组合以及旱伞草、美人蕉和芦苇3种植物的组合湿地系统比单一旱伞草湿地系统的净化效率更高；小粒径基质和混合种植湿地系统能够保持较稳定的净化效率。

Abstract:By constructed different modes of wetland systems, this paper investigated their purification efficiencies and persistence influenced, singly and in combination, by substrates made up and plant grown on. The results showed that the purification efficiency of wetland be increased by growing plant, and were higher in substrate mixed by sand and soil than substrate made of scree. The purification efficiencies of wetlands grown mixture of Cyperus alternifolius and Canna indica, and mixture of Cyperus alternifolius,Canna indica and Phragmites communis are higher than that of wetland grown Cyperus alternifolius singly. Small size substrate and mixture of plants are able to stable the purification efficiencies of wetlands.
