生物入侵模型中不同功能性反应函数对传播模式的影响

Spread Patterns of A Biological Invasion Model under Various Types of Functional Responses

研究了生物入侵模型中不同功能性反应函数对传播模式的影响作用。具体对二维捕食模型中种群在几类功能函数条件下的时空变化状态进行数值模拟,然后根据图像对入侵种群传播模式加以分析,得出了缀块入侵模式对特定功能性反应函数具有依赖性的结论。

In this paper,the spread patterns are investigated under the conditions of various types of functional responses in a biological invasion model.By means of extensive numerical simulations,a prey-predator system model in two spatial dimension is studied.According to the figures obtained,the spread patterns of prey and predator are discussed,the dependence of patchy invasion on specific functional response is discovered.
