Table 1 Indicators of block morphology.
Type | Feature | Indicator | Definition |
|---|---|---|---|
Morphological features | Building scale | Average built-up area (ABA) | The average area of land used by buildings within a grid |
Average building volume (ABV) | The average volume of buildings within a grid | ||
Average building height (ABH) | The average height of buildings within a grid | ||
Block compactness | Building density (BD) | The ratio of the total footprint area of buildings to the total area of the grid | |
Block morphology diversity | Variance in building height (VBH) | The standard deviation of building heights within a grid | |
Complexity of building form (CBF) | The ratio of average floor area to average perimeter | ||
Block spatial intensity | Floor area ratio (FAR) | The ratio of the total floor area of buildings to the area of the grid | |
Structure features | Block functional structure | Predominant land use (PLU) | The type of Points of Interest (POIs) that occupies the largest proportion within a grid |
Land use diversity (LUD) | The Shannon diversity index of different types of POIs within a grid | ||
Block connectivity | Street network density (SND) | The ratio of the total length of streets to the area of the grid | |
Block ecological structure | Green space ratio (GSR) | The ratio of green space area to the total area of the grid |
