摘要
以往的种群动力学模型均隐含假设性比为 1∶1,而实际上并非总如此 ,不同性别的出生和死亡是不完全相同的。文中就考虑了两性具有不同出生率和死亡率的种群动态问题。可以知道种群动态只是受雌性控制 ,与雄性无关。
Formerly, in the population dynamics models, it is assumed that the sex ratio is 1∶1, which is not always so in reality. The birth and death rates of different sex are different. In this paper, the population dynamics of different sex with different birth rate and death rate is studied. It suggest that the spreading process of one population is controlled by the female, and has no relation with the male.
