The concept of an ideal free distribution (IFD) is analyzed for the predator–prey system in an inhomogeneous ring-shaped habitat. Diffusion–reaction–advection equations were used to model multifactorial taxis with regard to various laws of prey growth. Relationships were established for the parameters at which the IFD occurs. Transformation of solutions was studied for the case where the parameters deviate from the IFD conditions and the origin of auto-oscillating regimes was considered.

具有多因素出租车的捕食者-猎物模型中的理想自由分布

分析了非均匀环形栖息地中捕食者-猎物系统的理想自由分布 (IFD) 的概念。扩散-反应-平流方程用于根据各种猎物生长规律对多因素出租车进行建模。为发生 IFD 的参数建立关系。在参数偏离 IFD 条件和考虑自振荡机制的起源的情况下研究了溶液的转换。
