【摘要】 通过调查滇池三个湖湾不同深度水层磷与铁的形态分布,研究三个湖湾内源磷的释放规律.结果表明,在海埂湾间隙水中,磷的释放强度远高于另外两个湖湾,根据水体中各种形态磷和铁的关系,推测出在这三个湖湾中,铁结合态磷是湖水悬浮物和沉积物中一种重要的可释放磷.更多还原

【Abstract】 The phosphorus and iron distributions of different water layers in three lake bays were investigated to study the release of internal phosphorus in the three lake bays. The results showed that the release intensity of phosphorus in Haigeng-bay was much higher than that in other two bays. According to the relations between various forms of phosphorus and iron, it was guessed that Fe-P was the main mobile phosphorus of suspensions and sediments in the three lake bays.更多还原
