Meaning
Horizontal level
1
Patch area
CA
The total patch area of a certain patch type reflects the difference of information flow such as species, energy, and nutrients during the period.
Plaque type
2
Percentage of landscape
PLAND
The ratio of a patch type to the total landscape area measures the dominant landscape elements of landscape components.
Plaque type
3
Number of patches
NP
The patch type indicates the total number of patches in a certain category.
Plaque type
4
Patch density
PD
Ratio of landscape area.
Plaque type
5
Landscape shape index
LSI
Refers to the total edge length of patch type or landscape divided by the minimum possible value of the total edge length.
Plaque type
6
Maximum patch area index
LPI
Refers to the proportion of the maximum patch area to the patch type area or landscape area.
Plaque type
7
Average patch area
AREA-MN
The total area of a patch divided by the total number of patches.
Plaque type
8
Degree of polymerization
AI
Refers to the number of nodes of patch type or landscape divided by the maximum number of nodes when the type or landscape first comes together.
Plaque type
9
Cohesion index
COHESION
Reflects the degree of aggregation of a certain type of patch or landscape.
Plaque type
10
Edge density
ED
The degree of edge segmentation is a direct response to the degree of landscape fragmentation.
Plaque type
11
Fractal dimension of perimeter area
PAFRAC
Refers to the relationship between the shape and area size of landscape patches. When the value is 1–2, the closer the value is to 1, the more regular the patch shape is
Landscape type
12
Spreading degree
CONTAG
Describes the degree or extension trend of different patches in the landscape.
Landscape type
13
Separation degree
DIVISION
Refers to the degree of separation of individual distribution of different patches in a landscape。
Landscape type
14
Shannon diversity index
SHDI
Refers to the diversity of landscape elements or ecosystem structure and function changing with time.
Landscape type
15
Shannon evenness index
SHEI
It reflects the uniformity of each patch in the area of landscape.
