Description

technical field [0001] The invention relates to the field of ecosystems, in particular to a method for simulating a shallow lake ecosystem model. Background technique [0002] A lake is a complex and changeable system of biophysical and chemical interactions among aquatic organisms, water flow, sediment, and pollutants. Its model equation is a mathematical relationship that reflects the mutual influence of its various elements. It is both the object to be studied and the A tool for studying lakes. According to its complexity, the lake model is divided into hydrodynamic model, water quality model and ecological model. Among them, the ecological dynamic model is mainly used to study the dynamic changes of various variables in the ecosystem and describe the time and space changes of species composition and species properties. The ecological model takes into account the temporal and spatial changes of various nutrients in the lake ecosystem, and describes the various change pr...

Problems solved by technology

[0004] (1) At present, domestic and foreign studies on the lake flow characteristics and eutrophication ecological dynamics of large deep-water lakes are relatively mature, while the model research on shallow-water lakes mainly focuses on hydrodynamic characteristics and water quality prediction. There are few studies on system dynamic simulation;

[0005] (2) The shallow lake ecosystem is a complex system. At present, the understanding of the ecological process in the construction of the ecosystem model is not perfect. For example, the growth process of phytoplankton is not only affected by environmental factors such as light, nutrients, and temperature. It is also limited by various biological factors such as its own population and submerged plants. The existing models do not fully consider the limiting factors of different biological ecological processes, resulting in low accuracy of model simulation.
