Ecological restoration by a multistage floating-bed system in a eutrophic urban river, China

摘要：

By constructing a multistage floating-bed system by combination of macrophytes, aquatic animals and aquamats ecobase for ecolgical restoration in a eutrophic urban river, the improvement of water quality and the dynamic variation of phytoplankton was investigated. The results showed that the average removal rates were 9.85％, 15.86％, 24.47％ and 12.75％, respectively, phytoplankton quantity was decreased by 22.82×104ind./L and Shannon-Weiner Index was increased by 0.11 averagely, after the restoration work in the demonstration area comparing to control area. The negative correlation between Shannon-Weiner Index of phytoplankton and TN(-0.77, P<0.01) showed that multistage system might effect phytoplankton indirectly through removing nutrients from river, which indicated that the employment of ecological restoration technology of multistage floating-bed system was effective in raising the ecological recovery efficiency of polluted water bodies.
