| Structure | Importance Value of Planted Species | The relative importance value of planted species was calculated by applying weighted dominance weighted value: Tree (3), Subtree (2), Shrub (1), and Herbaceous (0.5), normalized by the total weight (6.5) | 1-39% | 39-68% | 68-95% |
| Canopy Cover of Tree Layer | Total canopy cover of the tree layer | 70-95% | 40-70% | 0-40% |
| Crown density | Weighted dominance was assigned by vegetation layer (excluding herbaceous species) | 55-73% | 35-55% | 22-35% |
| Vertical Stratification | Vegetation was considered established when the canopy cover reached or exceeded 15% | 4 layers | 3 layers | 2 layers or less |
| Species Diversity | Species Richness | Species richness within the quadrat | 37-58 species | 21-37 species | 5-21 species |
| Species Evenness | H/In(S) | 0.48-0.72 | 0.3-0.48 | 0.09-0.3 |
| Shannon Diversity Index | − ∑ i = 1 s p i ln p i | 1.69-2.75 | 1.04-1.69 | 0.23-1.04 |
| Simpson Diversity Index | 1 − ∑ i = 1 s p i 2 | 0.62-0.89 | 0.35-0.62 | 0.09-0.35 |
| Species Composition | Proportion of Indicator Families | Importance value of Asteraceae, Poaceae, and Fabaceae | 0-3.3 | 3.3-17 | 17-37.1 |
| Number of Annual Herbaceous Species | Number of annual herbaceous species observed | 0-1 species | 1-5 species | 5-11 species |
| Number of Naturalized Species | Number of naturalized plant species observed | Not observed | 1-2 species | 2-5 species |
