摘　　要：在试验场地进行了表面流人工湿地中磷的降解及湿地不同部位基质和植物中磷含量的研究。结果表明,沿床体方向,基质中磷含量逐渐增加,植物各器官中磷含量逐渐降低,磷在表面流人工湿地中的降解是沿床体方向逐渐增强的。因此,可通过优化配比表面流人工湿地不同部位的基质和植物来提高人工湿地的除磷能力。In this research report, degradation and contents of phosphorus in different parts of a constructed wetland were studied. The results showed that： substrate adsorption to phosphorus increased and content of phosphorus in the plants＇ organs reduced along with bed length, while reduction of phosphorus enhanced along with the bed length. Through the research data collected. It may be recommended that removing ability of phosphorus from the wetland be obtained through optimization of the substrate as well as placement of various plants at different locations of constructed wetlands.
