中文摘要：

冬季通过对人工湿地系统采取保温措施，可有效维持和提高湿地内的温度，改善湿地净化效果：比较了种植不同植物湿地在不同运行方式下的污染物去除率。结果表明，通过控制湿地运行方式，可增高湿地系统温度和提高溶氧（D0）水平，从而提高COD、TN和TP的去除率；当水力停留时间（HRT）为5d时，湿地出水的TN和TP去除率分别达到72．5％和58．2％。

英文摘要：

Through adopting heat preservation measures on wetland system in winter, the temperature in the wetland could be maintained and raised effectively, and the wetland purification efficiency could be improved; the pollutant removal rates of different plant wetlands were compared under different operation way. Through controlling the wetland operation way, the temperature of wetland system and the level of dissolved oxygen could be enhanced, thus enhancing the removal rate of COD, TN and TP. The removal rates of wetland outflow water could reach 72.5% and 58.2% respectively when the hydraulic retain time was 5d.
