Spatiotemporal analyses of urban vegetation structural attributes using multitemporal Landsat TM data and field measurements

Table 5 Summary of some urban vegetation attributes within the study area in the city of Changchun, China

Imaging year	Vegetated pixel percentage (%)	Canopy cover (%)	Leaf area index	Basal area index (m²/ha)
1997	60.57	20.52	0.76	2.28
2004	55.06	14.29	0.50	1.69
2010	47.65	16.65	0.61	2.04

Vegetated pixel (pixels with >0% vegetation cover) percentage (%) = pixels with vegetation cover/all pixels in study area; canopy cover (%) = urban vegetation crown area/ study area; Leaf area index = one-side leaf area/ study area; Basal area index = total basal area/study area.
