Abstract:Aiming at Yingze Lake eutrophication, based on gathering data and long-time water quality monitoring, hydromatical model and water quality model, combined with a variety of biological processes were applied to established lake eutrophication coupled model, calibrated and verified by measurement of water quality data, the total nitrogen, total phosphorus, chlorophyll-a and transparency were selected to simulate, and concluded transport diffusion and spatial and temporal distribution of nutrients. Combined with the practical situation, from replenishment methods, replenishment frequency and changing lakes flexible structure, schemes on hydrodynamic condition and numerical simulation were put forward, and the modified effects of hydromatical condition and material transport diffusion of different schemes were studied. The results showed obvious spatial and temporal distribution of chlorophyll-a concentration which was between 0.035~0.105mg/L. Phytoplankton such as algae grow quickly,which was the peak period of algal bloom and water quality deterioration.Strategies such as increasing the hydraulic circulation and improving the inflow water quality would achieve good effects in water quality management.
