摘要:
A four-dimensional dynamic model is formulated to characterize the interactions among phytoplankton, submerged macrophyte, zooplankton, and fish in lake. The predation relationship is modeled by Beddington–DeAngelis functional responses derived from the classical Holling time budget arguments. Qualitative analyses of the global dynamics show that the system can generate very rich and complex dynamics including but not limited to bistable and chaotic phenomenon. We discuss the methods of biological control used to restrain the increase of phytoplankton and explore the refuge effect of macrophyte on zooplankton. Our analytical and simulation results suggest that, both the refuge constant and the density of the macrophytes are two key factors working on refuge effects, macrophytes provide shelter against predation for zooplankton, and planting macrophyte properly might achieve the purpose of controlling algae growth.
