摘要
提出了一类离散时间斑块单种群模型。结合推广的Kirchhoff矩阵树定理与Lyapunov方法,我们考虑了模型正平衡点的的稳定性,得到了容易验证的稳定性条件.
In this paper, a class of discrete-time patch single-species model is provided. By applying the extended Kirchhoff＇s Matrix Tree Theorem and Lyapunov method, the stability of the positive equilibrium point is considered and the stability condition which is easy to verify is given.
