基于根轨迹法的海洋生态模型稳定性分析
The Stability Analysis of the Marine Ecosystem Based on the Method of Root Locus
摘要
Abstract
A stability analysis is derrived for a nonlinear ocean ecological model. By using the method of generalized root locus the paper gets the conclusion that initial nutrient input influences the system stability, which is further proved by space trajectory. The analysis shows that the system is stable when the growth rate of phytoplankton and the initial nutrient input are both higher than the rate of mortality and the loss of nutrient. The system dynamic prosperities decrease with the increasing of the growth rate of phytoplankton and the initial nutrient input.关键词
