Practice of Water Ecological Restoration of Large Urban Eutrophication Lake——A case of study of Donghu Lake, Wuhan

Submerged macrophytes are the main components of lake ecosystems, and restoration submerged macrophyte community is an important part restoring ecosystems. Taking Water Ecological Restoration Projects in Wuhan Donghu Lake as example, Combined with current situation environment, phytoremediation area, species each sub-lake plant configuration plan were determined. The planting adopts process “selecting area - removing debris repelling fish ecologically improving substrate setting line planting”. Since project was implemented , grow well, coverage plants reaches more than 70%, transparency can reach 120cm, which meets design requirements basically.
