摘要:利用常微分方程定性和稳定性理论对具有Beddington-DeAngelis型功能反应函数的、食饵种群具有常数投放的捕食一被捕食模型进行了研究,得到解全局稳定和极限环存在的条件,剖析了相应的生态意义,并对特定系数下的系统进行了模拟.
ordinary differential equations DeAngelis type functional response, whose to study predator - prey model with Beddingtonprey population has a constant stocking rate, thus we can obtain the existing conditions of global stability of equilibrium point and limit cycle, which is of great significance for rational use and protection of natural resources, and to promote the sustainable development of ecological system. We further analyze the ecological significance of the corresponding system and use Mathematical to simulate the model, when coefficient is given.
