龙虎泡库区柱状沉积物中磷形态分级研究
|
摘要
通过对大庆龙虎泡水库的柱状沉积物中总磷和磷形态的研究,揭示了该库区底泥总磷和不同层位磷形态的分布规律。结果表明,沉积物中Ca-P(钙结合态磷)和Res-P(残渣磷)的含量较高,且Ca-P含量越高则Res-P含量越低,反之亦然。Ex-P(水溶态磷)虽然含量较低,但其向水体释放磷的可能性较大,是水体富营养化形成的重要因素之一。
Based on the research on total phosphorus and phosphorus forms in sediment column in Daqing Longhupao reservoir,the distribution rules of the total phosphorus and different phosphorus forms in the sediment layers were revealed.Ca-P and Res-P concentrations in sediments were relatively high.The higher Ca-P concentration was,the lower Res-P concentration could be,and vice versa.Although the Ex-P concentration was low,but the possibility of releasing phosphorus to the water was high,which was one of the important factors for eutrophication formation.
