摘要
沉积物中磷的形态不同,其生物活性也不同.本文讨论了三湘江和达理公寓附近池塘底泥中磷的各种存在形态,包括:可溶性磷(P_(sol))、磷酸钙(P_(Ca))、磷酸铝(P_(Al))、磷酸铁(P_(Fe))和闭蓄态磷酸盐(P_(O-P)),即为氧化物包裹的磷酸铝和磷酸铁,另外,还有部分有机磷(P_(org)).实验表明铝/铁结合态磷和有机磷是三湘江和池塘的主要赋存形态,对其富营养化影响最大.
Various phosphorus forms in the sediments showed different biological activity. This paper discussed the phosphorus forms in the sediments of Sanxiang river and a pond near Dali Flats, including： Psol,, Pca, PAl, PFe, Po-p （PFe and PAl packaged by oxides） and a part of Po~. The experiment indicated PA/PFe and organic phosphorus influenced the eutrophication most, which were chief forms of phosphorus in the sediments of Sanxiang river and the pond.
