The invention discloses a method, a device and a
system for evaluating the biological
bearing capacity of a marine ranch based on multimode
coupling. The method comprises the following steps: establishing a marine ranch hydrodynamic-ecological
coupling model to couple hydrodynamic and biogeochemical processes; establishing a marine ranch energy flow model, connecting a hydrodynamic force-ecological
coupling model to a
data input end of the model to output data, constructing a multimode coupling model, and coupling energy flow, hydrodynamic force and biogeochemical processes; and calculating the biological
bearing capacity of the marine ranch based on the multimode coupling model, and automatically evaluating the biological
bearing capacity. According to the method, the marine ranch energy flow, hydrodynamic force and biogeochemical processes are coupled, the accuracy of marine ranch biological bearing
capacity assessment is improved, the marine ranch biological bearing
capacity assessment module is arranged, the biological bearing
capacity assessment process is simplified, and the effectiveness and practicability of the biological bearing capacity assessment method are improved. The invention further discloses a device and a
system for evaluating the biological bearing capacity of the marine ranch, which have the above beneficial effects.
