摘　　要：文章主要分析了瓦埠湖沉积物中不同赋存形态的磷的稳定性和铝盐、铁盐控制瓦埠湖底泥释磷的效果。结果表明:底泥释磷总量在碱性条件下最大,中性条件下最小;铁磷、铝磷溶解量随pH值的升高均增加;钙磷溶解量随pH值的升高而降低。氯化铝、氯化铁对瓦埠湖底泥释磷的控制规律为:在酸性环境条件下控制的效果不明显,在中性环境条件下控制的效果较为显著,在碱性环境条件下控制的效果极为显著。The stability of different forms of phosphorus in sediments of Wabuhu Lake and the effects of P release control by using aluminum salt and iron salt are discussed in this paper.The results indicate that the total amount of the P release in the sediments of Wabuhu Lake is largest under alkaline conditions,while it is smallest under neutral conditions.The dissolved Fe-P and Al-P will increase with increasing pH,while the dissolved Ca-P will decrease under the same condition.The results of P release control by using aluminum chloride and ferric chloride are as follows： the effect is not obvious under the acidic conditions,but obvious under the neutral conditions,while the effect is extremely notable under the alkaline conditions.
