The alpha diversity indexes of leaf phyllosphere microbiota of different urbanization levels.

Urbanization Gradient	Species Richness	Shannon Diversity	Simpson Diversity
Suburban	888.67 ± 556.78 a	4.2 ± 1.86 a	0.86 ± 0.15 a
Developing	704.22 ± 136.74 ab	5.44 ± 0.55 a	0.98 ± 0.03 a
Urban	454.67 ± 47.84 b	4.77 ± 0.42 a	0.98 ± 0.01 a

Suburban, developing, and urban stand for the corresponding urbanization level of a sample. Values are mean ± standard deviation, and different lowercase letters after the same column of figures indicate significant differences.
