Therefore, it is of great significance to analyze the spatial and temporal distribution of phytoplankton through numerical simulation. In this paper, the spatial and temporal distribution of phytoplankton in Yubia Reservoir was analyzed using numerical simulation method.Firstly, the numerical model of Yubia Reservoir was established using the ocean model SCHISM, which includes hydrodynamic and water quality processes. The model used a grid resolution of 50m and a time step of 1 hour. Secondly, the model was calibrated and validated based on the measured data. Finally, the model was used to analyze the spatial and temporal distribution of phytoplankton in Yubia Reservoir.精品文档---下载后可任意编辑The results showed that the spatial distribution of phy...
