Table 5.
Overview of landscape indices used in this study.
| Scale | Index | Unit | Range | Representational meaning |
|---|---|---|---|---|
|
Type level |
(LPI) | % | 0 < LPI ≤ 100 | Representing the dominance of landscape types. |
| (COHESION) | None | 0 < COHESION < 100 | Reflecting the degree of patch accumulation in the same landscape type, the higher the value, the higher the patch cohesion. | |
| (DIVISION) | None | 0 ≤ DIVISION < 1 | Reflecting the degree of patch dispersion in the same landscape type. Value = 0, the landscape type is composed of a single patch; Value = 1, the landscape type is composed of many small patches. | |
| Landscape Level | (CONTAG) | % | 0<CONTAG ≤ 100 | Describing the degree of agglomeration or extension of different landscape types. |
| (SHDI) | None | 0 ≤ SHDI | To characterize the complexity of the landscape as a whole, the greater its value, the higher the complexity of the landscape as a whole. |
