Matrix models are widely used for demographic analysis of age and stage structured biological populations. Dynamic properties of the model can be summarized by the net reproductive rate R (0). In this paper, we introduce a new method to calculate and analyze the net reproductive rate directly from the life cycle graph of the matrix. We show, with examples, how our method of analysis of R (0) can be used in the design of strategies for controlling invasive species.
矩阵模型被广泛用于对年龄和阶段结构的生物种群进行种群统计学分析。该模型的动态特性可以用净繁殖率R(0)来概括。在本文中，我们介绍了一种直接从矩阵的生命周期图计算和分析净繁殖率的新方法。我们通过实例展示了我们对R(0)的分析方法如何用于入侵物种控制策略的设计。
