栖息地破碎化:斑块破坏其邻居的可能性
Habitat fragmentation: the possibility of a patch disrupting its neighbor
摘要:
本文从Fisher-Kolmogorov-Petrovskiii-Piskunov方程出发,对扩散种群进行建模。根据这个模型,主要的结果是,系统中两个相连的斑块并不总是相互贡献。具体地说,在小碎片旁边插入一个大碎片对小碎片内的生命总是有利的,而在大碎片旁边插入一个非常小的碎片对大碎片内的生命可能是不利的。这一结果,得到均匀破碎的区域,是可能的,从一般情况下的最小尺寸的两个补丁系统的表达式。这个表达式本身是一个有趣的结果,因为它允许研究本工作中未包括的其他特性。
英文摘要:
This paper starts from the Fisher-Kolmogorov-Petrovskii-Piskunov equation to model diffusive populations. The main result, according to this model, is that two connected patches in a system do not always contribute to each other. Specifically, inserting a large fragment next to a small one is always positive for life inside the small patch, while inserting a very small patch next to a large one can be negative for life inside the large fragment. This result, obtained to homogeneously fragmented regions, is possible from the general case expression for the minimum sizes in a system of two patches. This expression by itself is an interesting result, because it allows the study of other characteristics not included in the present work.
