The current lake water environment treatment still faces the problem that the actual improvement effect of lake water quality does not correspond to the expected project plan,especial-ly urban shallow lakes,which are affected by external pollution,sediment release,rainfall impact and other factors,and respond to disturbances in the treatment effect.Therefore,it is particularly important to carry out multi-scenario effect evaluation for the water environment treatment of ur-ban shallow lakes.Using the hydrodynamic water quality model,taking Moshui Lake in Wuhan City as an example,a water quality and hydrodynamic model of a shallow lake is built.Based on the current data of meteorology and hydrology,urban development and construction,and lake pollution,based on the model calculation principle,COD,NH3-N,TP are studied.The change trend of pollutants,etc.,quantitatively analyze the accessibility of lake water quality under different working conditions,and evalu-ate the implementation effect of planned and proposed projects,in order to provide reference for the opti-mization of similar lake water environment treatment projects.
