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 phos-phorus from agricultural drainage by sediment retention, plant absorption and microorganism decomposition. The content of nitro-gen and phosphorus is biggest in the time of agricultural drainage. Farmland runoff is reduced through the wetlands, TP and TN fall to 0.022mg/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 pu-rification ability of N, P, TP and TN of CarexschmidtiiMeinsh com-munity 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 wet-land sediment content in CarexschmidtiiMeinsh community is low-est, 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 CarexschmidtiiMeinshis biggest than orther communities.
