摘　　要：利用现场水池实验法,设可提供生境的复合生态浮床、普通生态浮床、空白对照3组实验处理,对比研究复合浮床与普通浮床在影响浮游植物群落结构及水质净化、生态修复方面的特点和优势。结果表明:复合浮床对N、P的去除率高于普通浮床;复合浮床和普通浮床两者的净化修复作用可抑制水体中浮游植物的大幅度增长,且复合浮床更有助于增加浮游植物的多样性、提高水生态系统的稳定性。Three treatments （the compound ecological floating bed system （EFBS）, the general EFBS, and control with no phytoplankton ） were compared with field experiments in several ponds to study their effects on phytoplankton community structure and their characteristics during the process of water purification and ecological restoration. The results show that the compound EFBS leads to higher removal rates of N and P; both the compound and the general EFBS have purification and restoration effects, which can inhibit the substantial growth of phytoplankton in the water; and the compound EFBS shows a better performance in increasing the diversity of phytoplankton and improving the stability of the aquatic ecosystem.
