摘要

我们对通过区域物种库的弱迁移进行的地方群落集结进行了数值分析。在平衡状态下，地方群落由区域群落中的一个物种子集（"小群"）组成。我们的分析表明，这些小群的相互作用网络呈现出非简单的结构。具体来说，我们展示了对称相互作用情况下小群相互作用矩阵的明显嵌套结构，以及不对称群落中的超均匀结构。

Numerical Study of Interaction Network Structures in Competitive Ecosystems

We present a numerical analysis of local community assembly through weak migration from a regional species pool. At equilibrium, the local community consists of a subset ("clique") of species from the regional community. Our analysis reveals that the interaction networks of these cliques exhibit nontrivial architectures. Specifically, we demonstrate the pronounced nested structure of the clique interaction matrix in the case of symmetric interactions and the hyperuniform structure seen in asymmetric communities.
