Quantifying Effects of Spatial Heterogeneity of Farmlands on Bird Species Richness by Means of Similarity Index Pairwise

Table 2

Ranking of farmland spatial heterogeneity according to landscape and land-uses characteristics, where FSH is farmland spatial heterogeneity.

FSH description	FSH rank	Terrain slope	Marginal vegetation	Land-use diversity
Very heterogeneous	4	None, slight, mean	Linear + point	>1.0
Heterogeneous	3	None, slight, mean	Linear	0.8 < 1.0
Homogeneous	2	None, slight, mean	Point	0.6 < 0.8
Very homogeneous	1	None, slight	None	<0.6
