Modeling water quality parameters in marine ecosystems affected by oxygen deficiency
摘要
This paper presents a mathematical model (COPSTZ) that simulates the interactions within a marine ecosystem, focusing on six key compartments: dissolved oxygen, organic pollutants, phytoplankton, salinity, temperature, and zooplankton. The model specifically explores how reductions in dissolved oxygen impact the survival of interacting planktonic populations. By solving the model equations both analytically and numerically, the equilibrium states are identified and their stability is analyzed. The analysis of the model results reveals that decreases in dissolved oxygen concentration occur because of the combined effects of salinity, organic pollutants, and plankton. Additionally, the model’s predictions for dissolved oxygen, plankton, zooplankton, and organic pollutants align with findings from other studies. The study concludes that dissolved oxygen levels in marine ecosystems can be improved and the negative impacts of salinity reduced through the strategic use of coastal vegetation and the optimization of plankton nutrient availability.
