包括根茎生长的植被格局的一般模型

A general model for vegetation patterns including rhizome growth

Daniel Ruiz-Reynés, Francesca Schönsberg, Emilio Hernández-García, Damià Gomila

摘要:

植被格局是世界范围内观察到的一种自然现象,通常由空间分布的反馈驱动。然而,克隆植物的空间定殖机制,由根状茎的生长驱动,通常不考虑在原型模型。在这里,我们提出了一个一般方程的植被密度,包括所有主要的克隆生长功能,以及导致空间自组织的基本成分。这个通用模型再现了一个完整的详细模型的克隆生长的相图。讨论了模型各项与克隆生长机制的关系。

英文摘要:

Vegetation patterns, a natural phenomenon observed worldwide, are typically driven by spatially distributed feedback. However, the spatial colonization mechanisms of clonal plants, driven by the growth of a rhizome, are usually not considered in prototypical models. Here we propose a general equation for the vegetation density that includes all main clonal-growth features as well as the essential ingredients leading to spatial self-organization. This generic model reproduces the phase diagram of a fully detailed model of clonal growth. The relation of each term of the model with the mechanisms of clonal growth is discussed.
