The scoring system of the eco-environmental quality value (Feizizadeh & Blaschke 2013)
| Rank . | EBV range . | Eco-environment type . | Topographical condition . | Vegetable cover/Landcover . | Humidity and heat . |
|---|---|---|---|---|---|
| I | 450–500 | High coverage ratio, broadleaf, conifer and broadleaf mixed eco-environment type | Moderate mountains (1,000–1,200 m) | Evergreen broadleaf forest; tree cover >90% | 70–80% shady and cool |
| II | 400–450 | Moderate coverage ratio, conifer and broadleaf mixed eco-environment type | Low mountains (500–1,000 m) | Subtropical conifer and broadleaf, mixed forest, deciduous, broadleaf forest; tree cover is 80–90% | 60–70% shady and cool |
| III | 350–400 | Low coverage ratio, conifer, eco-environment type | Low mountains (500–1,000 m) | Conifer forest: fir, horsetail forest | 40% shady |
| IV | 300–350 | Shrub eco-environment type | Various hilly and mountainous lands | Evergreen broadleaf forest, shrub | 50–60% warm |
| V | 250–300 | Meadow and brushwood, eco-environment type | Top of moderate mountains ( > 1,200 m) | Meadow, bunch grasses (Gramineae) | 30% cool |
| VI | 200–250 | Economic forest, eco-environment type | Costal low hills and uplands, valley | Orchard garden, tea garden, bamboo | 30% warm |
| VII | 150–200 | Wetland eco-environment type | Plain farmland | Irrigation farming | 50% dry and heat |
| VIII | 100–150 | Arid and barren land, eco-environment type | Peninsula, sand beach | Dry farming | 20% dry and heat |
| IX | 50–100 | Artificial construction, eco-environment type | Plain | Residential area, buildings | 20% dry and heat |
