人工载体改善富营养水体水质的研究进展

The summary of improvement of eutrophic waters by artificial substrate

水体富营养化是我国面临的主要水环境问题之一,以沉水植被恢复为核心的富营养水体生态系统修复技术被认为是生态修复的核心技术,但沉水植被的恢复需要一定的基础环境,如光照、营养盐等。因此,在水生态修复中,如何有效抑制浮游植物的生长,提高水体透明度是沉水植被重建的先决条件之一。附着生物是水生态系统中重要的组成部分,在营养盐的循环中扮演着重要角色。人工载体可以促进附着生物群落的建立,利用人工载体提高水体附着生物生产力和营养盐滞留能力,改善富营养水体水质,为后续的沉水植被恢复提供基础环境。

Eutrophication is one of the major water environmental problems in China.The restoration of eutrophic water ecosystems with submerged vegetation restoration is considered to be the core technology of ecosystem restoration.However,the restoration of submerged macrophytes requires a certain basic environment.Such as light,nutrients and so on.Therefore,inhibition the growth of phytoplankton and improvment the transparency of water is one of the prerequisites in the reconstruction of submerged macrophytes.Periphyton is an important part of the aquatic ecosystem and play an important role in the circulation of nutrients.Artificial substrates can promote the establishment of periphyton.Using artificial substrates to improve the establishment of periphyton and removal of nutrients from the eutrophic waters,improving the water quality of eutrophic waters,and provide a basic environment for the restoration submerged vegetation.
