Factor Type	Metric Name	Acronym	Description
Park shape index	Index of nearly circular shape	CIRCLE	The smaller the value is, the closer the patch is to the circle; the more significant the matter is, the closer the patch is to the strip.
	Park Shape index	SHAPE	equals 1 when all patches are circular; increases with the complexity of patch shapes; independent of patch size
	Park Area	AREA	Area of parks
	Park Perimeter	PERIM	Circumference of the park
Landscape Composition	Percentage of bare land in the park area	Pb	Percentage of the bare land in the park
	Percentage of impervious surface area in the park area	Pi	Percentage of impervious surface area in the park
	Percentage of vegetation in the park area	Pv	Percentage of all kinds of vegetation area in the park
	Percentage of water bodies in the park area	Pw	Percentage of the water body area in the park
	Area of impervious surface in the park	Ci	Size of impervious surface area in parks
	Area of bare land in the park	Cb	Area of bare land in parks
	Area of vegetation in the park	Cv	The total area of all vegetation in parks
	Area of water body in the park	Cw	Area of water bodies in parks
Landscape Configuration	Aggregation index	AI	Account for the maximum possible number of like adjacencies given any landscape composition
	Shannon’s evenness index	SHEI	Diversity measure, which considers the only evenness of patch sizes, not the number of patches
	Simpson’s patch diversity	SHDI	Diversity measure, which equals minus the sum of the proportional abundance of each patch type multiplied by the ln of that proportion
	Shannon’s Diversity Index	SIDI	Diversity measure, which equals 1 minus the sum of the squared proportional abundance of each patch type
	Patch Cohesion Index	COHESION	The measure of the physical connectedness of the focal land cover class
	Interspersion & Juxtaposition Index	IJI	The measure of evenness of patch adjacencies equals 100 for even and approaches 0 for uneven adjacencies.
	Perimeter–area fractal dimension	PAFRAC	Patch shape complexity measure, which approaches 1 for shapes with simple perimeters and 2 for complex shapes
	Mean Perimeter-Area Ratio	PARA_MN	Patch shape complexity measures the mean value of the patch perimeter area ratio.
	Mean Fractal Dimension Index	FRAC_MN	Average patch shape complexity measures approach 1 for simple shapes and 2 for complex shapes; it reflects shape complexity across various spatial scales (patch sizes).
	Mean shape index	SHAPE_MN	A patch-level shape index averaged over all patches in the landscape.
	Mean fractal dimension	AREA_MN	Size of the patches
	Landscape shape index	LSI	Landscape shape index, landscape shape index of the landscape in the spatial unit
	Patch density	PD	The number of patches per park, the larger the patch density value is, the smaller the patch size is, and the higher the fragmentation degree is.
	Number of patches	NP	Total number of patches of landscape type
