| 摘 要： | 对磷在不同的水生植物系统中的重新分配进行了研究。结果表明，浮水植物（青萍和紫萍）吸收的磷主要来自于上覆水，而沉水植物（黑藻和水花生）吸收的磷直接来自于沉积物。沉积物中的解磷细菌促进了沉积物中的磷向上覆水中释放，从而降低了沉积物中的总磷含量。不同的水生植物处理系统中，沉积物微生物生物量及解磷细菌的数量均有差异，且沉积物的磷含量与解磷菌的数量呈现出一种负相关关系。

| Abstract: | Phosphorous is a key nutritious element that affects waterbody eutrophication.Phosphorus redistribution in plant-overlay water-sediment system with different hydrophytes has been studied.Results showed that phosphorous absorbed by Lemna minor and Spirodela polyrhiza came from overlay water,while phosphorous absorbed by Hydrilla verticilata and Alternanthera philoxeroides came mainly from sediment.Phosphate bacteria in sediment accelerates phosphorous release into overlay water,resulting in the reduction of phosphorus content in the sediment.In different hydrophytes environment,there are different amount of the microbial biomass and phosphate bacteria.Phosphorus content in the sediment is right opposite to the amount of phosphate bacteria. |
