Connectivity Evaluation and Planning of a River-Lake System in East China Based on Graph Theory
Table 1
Connectivity evaluation index system.
| Classification | Index | Meaning | Evaluation content |
| Determinant index | Edge Connectivity | The minimum number of edges that must be removed to make a graph unconnected. | Evaluate the connectivity of the entire stream network. |
| Evaluative index | Edge-Node rate
| Divide the number of rivers by the number of lakes and junctions. | Evaluate the number of rivers that each node occupies. | Connectivity Reliability
| The possibility of the Edge Connectivity remains unchanged if one edge is randomly disconnected in a system with Edge Connectivity λ. | Evaluate the reliability of a stream network in the current Edge Connectivity level. The range is from 0 to 1 | Edge Weights (m2) | River section. | Evaluate the discharge capacity of rivers. |
