Landscape metrics | Formula | Decription |
PD |
| The number of patches per unit area of a certain type; Positive correlation with fragmentation degree; Where N is the number of landscape patches and A is the total area of the landscape, the same below. |
ED |
| Length of Patch Boundary in Unit Area; Where E is the total length of the boundary in the landscape, the same below. |
LSI |
| Reflecting the development degree of landscape types. |
CONTAG |
| Aggregation degree or extension trend of different landscape types; Where pi is the area percentage of patch type i, gij is the number of adjacent patches between patch type i and patch type j, m is the total number of patch types, the same below. |
SHDI |
| Indicators reflecting the diversity of landscape types. |
SHEI |
| The SHEI value tends to be 1, indicating that the dominance is decreasing. |
