摘要
本文根据生态学实验现象研究了一类二种群捕食者-食饵系统,其中捕食者对食饵有性别偏食情形.建立了相应的数学模型,并对该模型的有关性态进行了分析.
This paper is devoted to establish a prey-predator system model with sexual fa- voritism, which come from an ecology experiment. We have analyzed its persistence and stability, obtained sufficient conditions for persistence and stability.
