| 摘 要： | 采用磷的分级方法研究苦草移植后生长过程中沉积物不同的磷赋存形态(NH4Cl-P, BD-P, NaOH-P和HCl-P)以及总磷的变化,同时结合野外人工恢复的水草区域采样的结果,进一步分析了野外条件下沉水植物狐尾藻(Myriophyllum spicatum L.)对磷赋存形态的影响,结果表明,沉水植物能够有效的降低沉积物中磷的含量,而且水生植物对磷的不同赋存形态的影响并不相同,其中,BD-P是受沉水植物影响最为明显的磷赋存形态.

| Abstract: | In the paper, measured were submerged macrophyte (Vallisneria spirlis) of manual plant on the different phosphorus pools(NH_ 4Cl-P,BD-P,NaOH-P and HCl-P)in sediment, and the filed analysis in the sediment with submerged macrophyte (Myriophyllum spicatum L.) was also done. The results both show that the submerged macrophyte can decrease the concentration of the total phosphorus in sediment by assimilating phosphorus in sediment as nutrient, but may have the different effect on the different phosphorus pools, and the effect on BD-P is the most significant. |
