Table 7 Ecological landscape indicator selection
Name | Level | Properties | Ecological Significance55 |
|---|---|---|---|
Percentage of Landscape, PLAND | Class | Structure | Characterizes the dominance of patch types in the landscape, influencing habitat quality and ecological functions. |
Largest Patch Index, LPI | Class、Landscape | Structure | Indicates the control exerted by the largest patch over the landscape/type, reflecting disturbance intensity from environmental change. |
Edge Density, ED | Class、Landscape | Edge | Edge complexity and density, affecting species diversity and habitat suitability. |
Interspersion and Juxtaposition Index, IJI | Class、Landscape | Connectivity | Spatial arrangement and adjacency of patch types, reflecting inter-patch relationships and ecological diversity. |
Contagion Index, CONTAG | Landscape | Aggregation | Aggregation (non-random distribution) of patches, influencing material cycling and energy flow in ecosystems. |
Shannon’s Diversity Index, SHDI | Landscape | Heterogeneity | Characterizes richness and evenness of patch types in the landscape, affecting ecosystem stability. |
Patch Density, PD | Landscape | Fragmentation | Higher fragmentation values indicate greater landscape fragmentation, leading to habitat isolation and impacting species survival/dispersal. |
Fractal Dimension, FD | Landscape | Shape | Characterizes patch shape complexity, affecting material exchange between patch interiors/exteriors and species distribution. |
