摘　　要：湿地通过植物吸收、湿地底泥的截留吸附和微生物降解来净化农田径流中携带的N、P污染。农田退水期湿地中的N、P含量最大,流经湿地的农田径流,5月TP和TN含量下降到0.022mg/L和0.95mg/L,7月TP和TN含量下降到0.024mg/L和0.93mg/L;不同群落对N、P的吸收净化能力有所不同,修氏苔草群落在5月植物样品中的TP和TN含量分别为9.20mg/L和18.00mg/L,7月植物样品中的TP和TN含量分别为10.65mg/L和19.35mg/L均高于其它植物样品;修氏苔草群落在5月湿地底泥样品中的TP和TN含量分别为0.26mg/L和1.16mg/L,7月湿地底泥样品中的TP和TN含量分别为0.21mg/L和1.06mg/L均低于其它湿地底泥样品,修氏苔草群落对N、P的阻控能力明显高于其它群落。Wetlands have the capacity to purify nitrogen and phosphorus from agricultural drainage by sediment retention,plant absorption and microorganism decomposition.The content of nitrogen and phosphorus is biggest in the time of agricultural drainage.Farmland runoff is reduced through the wetlands,TP and TN fall to0.022mg/L and 0.95mg/L in may,TP and TN fall to 0.024 mg/L and 0.93mg/Lin July.Different communities is different on the purification ability of N,P,TP and TN of Carexschmidtii Meinsh community is biggest,9.20 mg/L and 18.00 mg/Lin May and 10.65 mg/L and 19.35 mg/L in Julythan other community;TP and TN of wetland sediment content in Carexschmidtii Meinsh community is lowest,0.26 mg/L and 1.16 mg/L in May and 0.21 mg/L and 1.06mg/L in July than other wetland sediment.The purification fuction of Carexschmidtii Meinshis biggest than orther communities.
