森林景观斑块耦合网络的构建

摘要

In order to satisfy requirements of sustainable forest management, it is necessary to carry out the study of forest management from the angle of landscape scale. By taking west Dongting lake area as the example, using the method of graph theory, the forest landscape patches coupling network for the area was set up, through taking the patches as the network nodes and the coupling strength values among plaques as the inter-node edge-weight values. Further,the stability and invulnerability of the forest landscape ecology system in the area were penetratingly analyzed.%森林景观斑块之间呈现不同程度的边缘效应，不同森林景观类型斑块的耦合作用强度不同。为了满足森林可持续经营的要求，需要在景观尺度上开展森林经营研究。以西洞庭湖区为例，运用图论的方法，把森林景观斑块作为节点、斑块之间的耦合作用强度作为节点间边权，从而构建该区森林景观斑块耦合网络。运用复杂网络理论，进一步深入分析了森林景观生态系统的稳定性和抗毁性。
