Study on ecological restoration in near-shore zone of a eutrophic lake, Wuli Bay, Taihu Lake

摘要

A two-year restoration period, large-scale ecological restoration demonstration engineering project was carried out in the near-shore zones of Wuli Bay, Taihu Lake. Various methods to restore the aquatic biodiversity and prevent ecological degradation were employed and their effects on water quality and aquatic plants were investigated. The results showed that water quality had been significantly improved in the demonstration zones. The concentrations of TN and TP were about half of those of the reference site in Wuli Bay. The water transparency was 30cm higher than that in the reference site. The species, cover and biomass of aquatic plants were also significantly increased in the demonstration zones.
