Landscape metrices used in this study area following McGarigal et al. (2012) and Smiraglia et al. (2015)
Acronym | Metric | Description |
---|---|---|
PLAND | Percentage of landscape | Proportion of the landscape occupied by certain LULC class (0 < PLAND < 100) |
NP | Number of patches | Number of patches in the landscape of the same LULC class (N ≥ 1) |
LPI | Largest patch index | Percentage of the landscape comprised by the largest patch of the corresponding LULC class (0 < LPI < 100) |
ED | Edge density | Total length of edge of a certain LULC class per unit area (m/ha). ED ≥ 0, and 0 when there is edge in the landscape |
AREA_MN | Mean patch size | Mean area of patches of the same LULC class (m2) |
SHAPE_AM | Area‐weighted mean shape index | It measures the complexity of patch shape of a particular LULC class compared to a standard shape (square), by weighting patches according to their size. It equals 1 when all patches are square and increase with complexity of patch shapes. |
ENN_MN | Mean Euclidean nearest neighbor distance | Mean of minimum edge‐to‐edge distances to the nearest neighboring patch of the same type of a certain LULC class (m) |
IJI | Interspersion and juxtaposition index | Measure of evenness of patch adjacencies equals 100 for even and approaches 0 for uneven adjacencies |
AI | Aggregation index | Percentage of neighboring pixel of the same LULC class, based on single‐count method |
