Landscape metric | Description |
Percentage of landscape 0 < PLAND ≤ 100 | Landscape size occupied by a certain land cover type |
Mean Patch Area AREA_MN > without limit | The arithmetic mean size of the given patch type |
Number of Patches NP > 1 without limit | Total patches of the respective class |
Patch Density PD > without limit | Patch density is a function of Total landscape area obtained by dividing the total patches of the patch type (NP) by total landscape area and then convert to 100 hectares |
Landscape Shape Index 0 < LSI ≤ 100 | Denotes the shape of the patches of a landscape |
Fractal Index Distribution (FRAC_MN) | Obtained by doubling the logarithm of patch perimeter (m) and then dividing it by the logarithm of the patch area (m2) |
Simpson’s Diversity Index (SIDI) | Obtained by subtracting the sum across all patch type squared from 1 |
Shannon’s diversity index SHDI ≥ 0 | equals minus the sum, across all patch types, multiplied by the proportion |
Perimeter-Area Fractal Dimension 1 ≤ PAFRAC ≤ 2 | Obtained by dividing 2 by the regression slope line obtained by regressing the patch area’s logarithm against the patch perimeter’s logarithm |
Landscape fragmentation index (LFI) | Obtained by dividing the total area of each class by the number of patches |
