水生植物对沉积物中各赋存形态磷的影响研究

Effects of Aquatic Plants on the Characteristics of Phosphorus in Sediments

简要概述了国内外关于水生植物对沉积物中磷营养盐的影响研究现状,研究结果表明:水生植物能减少沉积物再悬浮,抑制颗粒态磷的活化;研究选用的水生植物多数是沉水植物,对挺水植物的研究相对比较少,而对于沉水植物与挺水植物两种不同类型的水生植物对比研究就更少。因此,应对不同种类水生植物对各赋存形态磷的影响效果做对比研究,以便提出更有效的降低沉积物中磷释放的措施。

The article gives a brief overview of the research on the effects of aquatic plants on the characteristics of phosphorus in sediments in the world; the results of the research show that： aquatic plants can reduce the resuspension of sediment, and inhibit the activation of particulate phosphorus; most of aquatic plants in the research are submerged plant. The research on emergent plants is relatively less, and the contrast research on submerged plant and emergent plants is less. Therefore, we should have a contrastive study of the effect of different aquatic plants on the characteristics of phosphorus in sediments, so as to put forward more effective measures to reduce the release of phosphorus.
