中文摘要：

以巢湖十五里河河口湿地土壤为研究对象,选用PAM（J）、PAM＋生物炭（SJ）和PAM＋泥炭（NJ）为土壤结构改良剂,研究改良剂对淹水条件下培养后土壤水稳性团聚体数量、土壤抗悬浮能力和土壤磷释放的影响。结果表明,四种处理（CK、NJ、J和SJ）〉0.25 mm水稳性团聚体含量大小顺序为：J（58.73±0.57%）〉SJ（48.27±3.58%）〉NJ（34.47±2.02%）〉CK（2.31±0.15%）。在室内风浪扰动模拟实验中,扰动后上覆水体悬浮物浓度（SS）和水体磷浓度的大小顺序均是：CK〉NJ〉J〉SJ,且CK显著大于NJ、J和SJ。添加PAM（J）、PAM＋生物炭（SJ）和PAM＋泥炭（NJ）不仅能显著提高〉0.25 mm研究区湿地土壤水稳性团聚体的含量,也能显著增强风浪扰动下淹水土壤的抗悬浮能力,进而显著降低淹水后土壤磷释放能力,其中以添加PAM＋生物炭组合提升淹水后湿地土壤抗悬浮和降低磷释放能力的效果最佳。

英文摘要：

Soils were collected from estuary wetland of Shiwuli River in the Chaohu Lake region. Influences of PAM（J）, PAM＋biochar（SJ） and PAM＋peat（NJ） amendments on soil aggregates, anti-suspension and phosphorus release were studied after flood incubation. The results showed that 〉0.25mm soil water-stable aggregate contents were in the order ： J（58.73±0.57%）〉SJ（48.27±3.58%）〉NJ（34.47±2.02%）〉CK （no modifier treatment）（2.31±0.15%）.On the laboratory simulated experiment of wind effect, soil suspension contents and total phosphorus in water were in the order ： CK〉NJ〉J〉SJ, CK was significantly higher than the else. Compared to CK, J, SJ and NJ increased the contents of 〉0.25mm water-stable aggregates,and enhanced the capability of soil anti-suspension, moreover, obviously reduced soil phosphorus release into waters. The SJ, was the best treatment to promote the capability of soil anti-suspension and reduce the phosphorus release into water.
