基于ALife的鼠类及天敌数量变化模拟

Simulation of Variation Rules of Rats and Natural Enemy Based on Artificial Life

研究鼠类及其天敌的数量变化规律,对鼠害防治工作有重要意义。文章以鼠和天敌为模型构建了一个基于人工生命的捕食者-食饵模拟系统。通过建立环境和生命体的模型,规定环境与生命体之间的交互规则,以及系统的运行规则,成功构建系统并研究了鼠类和天敌之间一系列的数量变化关系。验证了天敌对鼠在数值反应的同时,功能反应也在起作用;天敌数量和天敌食物中鼠的比例随鼠类数量同方向变动,它们作用的结果是使系统趋于平衡。

The research about the variation rules of the Rats and Enemy number is very important to control rat＇s damage. A simulation system is designed which consists of prey （rats） and predator （enemy） based on Artificial Life. First we present the properties of the environment and the life,then we identify the interaction protocol between life and environment,the last one is system run. The system output is various attributions of rats and enemy. This analysis shows that the numerical response and functional response of enemy in the rats,rats＇ number,enemy number and the percentage of rats in the enemy food increase or decrease in the same direction,all of those make the system reach equilibrium.
