人口老龄化对资源限制的影响
The effect of limiting resources in aging populations
摘要：
在大多数模型中，承载能力的概念对于防止无限增长至关重要。尽管它引入了大量的死亡，但Verhulst项在模拟中的实际影响往往没有考虑在内。一般来说，它仅仅被视为一个缩放参数，其功能是将模拟种群保持在计算机限制范围内。在这里，我们比较两种不同的实现的概念在Penna模型- Vehulst适用于所有个人（VA）和新生儿（VB）。当随机Verhulst死亡仅限于一个年龄组时，我们观察到某些模型特征的变化。
英文摘要：
The concept of a carrying capacity is essential in most models to prevent unlimited growth. Despite the large amount of deaths it introduces, the actual influence of the Verhulst term in simulations is often times not accounted for. Generally, it is treated merely as a scaling parameter that functions to keep simulated populations within computer limits. Here, we compare two different implementations of the concept in the Penna model - Vehulst applied to all individuals (VA) and to newborns only (VB). We observe variations in certain model features when random Verhulst deaths are restricted to a single age group.
